Instead of passing util and max between functions while computing the
utilization and capacity, store the former in struct sg_cpu (along
with the latter and bw_dl).
This will allow the current utilization value to be compared with the
one obtained previously (which is requisite for some code changes to
follow this one), but also it causes the code to look slightly more
consistent and cleaner.

The cppc_cpudata per-cpu storage was inefficient (1) additional to causing
functional issues (2) when CPUs are hotplugged out, due to per-cpu data
being improperly initialised.
(1) The amount of information needed for CPPC performance control in its
cpufreq driver depends on the domain (PSD) coordination type:
ANY: One set of CPPC control and capability data (e.g desired
performance, highest/lowest performance, etc) applies to all
CPUs in the domain.
ALL: Same as ANY. To be noted that this type is not currently
supported. When supported, information about which CPUs
belong to a domain is needed in order for frequency change
requests to be sent to each of them.
HW: It's necessary to store CPPC control and capability
information for all the CPUs. HW will then coordinate the
performance state based on their limitations and requests.
NONE: Same as HW. No HW coordination is expected.
Despite this, the previous initialisation code would indiscriminately
allocate memory for all CPUs (all_cpu_data) and unnecessarily
duplicate performance capabilities and the domain sharing mask and type
for each possible CPU.
(2) With the current per-cpu structure, when having ANY coordination,
the cppc_cpudata cpu information is not initialised (will remain 0)
for all CPUs in a policy, other than policy->cpu. When policy->cpu is
hotplugged out, the driver will incorrectly use the uninitialised (0)
value of the other CPUs when making frequency changes. Additionally,
the previous values stored in the perf_ctrls.desired_perf will be
lost when policy->cpu changes.
Therefore replace the array of per cpu data with a list. The memory for
each structure is allocated at policy init, where a single structure
can be allocated per policy, not per cpu. In order to accommodate the
struct list_head node in the cppc_cpudata structure, the now unused cpu
and cur_policy variables are removed.
For example, on a arm64 Juno platform with 6 CPUs: (0, 1, 2, 3) in PSD1,
(4, 5) in PSD2 - ANY coordination, the memory allocation comparison shows:
Before patch:
- ANY coordination:
total slack req alloc/free caller
0 0 0 0/1 _kernel_size_le_hi32+0x0xffff800008ff7810
0 0 0 0/6 _kernel_size_le_hi32+0x0xffff800008ff7808
128 80 48 1/0 _kernel_size_le_hi32+0x0xffff800008ffc070
768 0 768 6/0 _kernel_size_le_hi32+0x0xffff800008ffc0e4
After patch:
- ANY coordination:
total slack req alloc/free caller
256 0 256 2/0 _kernel_size_le_hi32+0x0xffff800008fed410
0 0 0 0/2 _kernel_size_le_hi32+0x0xffff800008fed274
Additional notes:
- A pointer to the policy's cppc_cpudata is stored in policy->driver_data
- Driver registration is skipped if _CPC entries are not present.

Considering only the currently supported coordination types (ANY, HW,
NONE), this change only makes a difference for the ANY type, when
policy->cpu is hotplugged out. In that case the new policy->cpu will
be different from ((struct cppc_cpudata *)policy->driver_data)->cpu.
While in this case the controls of *ANY* CPU could be used to drive
frequency changes, it's more consistent to use policy->cpu as the
leading CPU, as used in all other cppc_cpufreq functions. Additionally,
the debug prints in cppc_set_perf() would no longer create confusion
when referring to a CPU that is hotplugged out.

For errors parsing the _PSD domains, a separate domain is returned for
each CPU in the failed _PSD domain with no coordination (as per previous
comment). But contrary to the intention, the code was setting
CPUFREQ_SHARED_TYPE_ALL as coordination type.
Change shared_type to CPUFREQ_SHARED_TYPE_NONE in case of errors parsing
the domain information. The function still returns the error and the caller
is free to bail out the domain initialisation altogether in that case.
Given that both functions return domains with a single CPU, this change
does not affect the functionality, but clarifies the intention.

The Tegra194 CPUFREQ driver sets the CPUFREQ_NEED_INITIAL_FREQ_CHECK
flag which means that the CPUFREQ framework will call the 'get' callback
on boot to determine the current frequency of the CPUs. Therefore, it is
not necessary for the Tegra194 CPUFREQ driver to internally call the
tegra194_get_speed_common() during initialisation to query the current
frequency as well. Fix this by removing the call to the
tegra194_get_speed_common() during initialisation and simplify the code.

The CPUFREQ driver framework references each individual CPUs when
getting and setting the speed. Tegra186 has 3 clusters of A57 CPUs and
1 cluster of Denver CPUs. Hence, the Tegra186 CPUFREQ driver need to
know which cluster a given CPU belongs to. The logic in the Tegra186
driver can be greatly simplified by storing the cluster ID associated
with each CPU in the tegra186_cpufreq_cpu structure. This allow us to
completely remove the Tegra cluster info structure from the driver and
simplifiy the code.

The Tegra186 CPUFREQ driver is using the policy->driver_data variable to
store and iomem pointer to a Tegra186 CPU register that is used to set
the clock speed for the CPU. This is not necessary because the register
base address is already stored in the driver data and the offset of the
register for each CPU is static. Therefore, fix this by adding a new
structure with the register offsets for each CPU and store this in the
main driver data structure along with the register base address. Please
note that a new structure has been added for storing the register
offsets rather than a simple array, because this will permit further
clean-ups and simplification of the driver.

only when CONFIG_COMMON_CLK=y. One possible fix is to add the Kconfig

for scmi cpufreq, it is preferrable to avoid that.
Let us just conditionally compile out the offending call to
devm_of_clk_add_hw_provider. It also uses the variable 'dev' outside
