Atm we're zeroing out fields in MG_PLL_BIAS and MG_PLL_TDC_COLDST_BIAS
if refclk is 38.4MHz, whereas the spec tells us to preserve them.
Although the calculated values mostly match the register defaults even
for the 38.4MHz case, there are some differences wrt. what BIOS
programs (I noticed at least differences in the MG_PLL_BIAS/IREFTRIM and
MG_PLL_BIAS/BIASCAL_EN fields). In the lack of further info on how to
program these fields, just do what the spec says and preserve the BIOS
state.
v2:
- Preserve the BIOS programmed reg fields instead of programming them.

This implements the "MG PLL Programming" sequence from our spec. The
biggest problem was that the spec assumes real numbers, so we had to
adjust some numbers and calculations due to the fact that the Kernel
prefers to deal with integers.
I recommend grabbing some coffee, a pen and paper before reviewing
this patch.

- Small checkpatch issues.
- Rebase.

This commit introduces the definitions for the ICL clocks and adds the
basic functions to the shared DPLL framework. It adds code for the
Enable and Disable sequences for some PLLs, but it does not have the
code to compute the actual PLL values, which are marked as TODO
comments and should be introduced as separate commits.
Special thanks to James Ausmus for investigating and fixing a bug with
the placement of icl_unmap_plls_to_ports() function.
v2:
- Rebase around dpll_lock changes.
v3:
- The spec now says what the timeouts should be.
- Touch DPCLKA_CFGCR0_ICL at the appropriate time so we don't freeze
the machine.
- Checkpatch found a white space problem.
- Small adjustments before upstreaming.
v4:
- Move the ICL checks out of the *map_plls_to_ports() functions
(James)
- Add extra encoder check (James)
- Call icl_unmap_plls_to_ports() later (James)
v5:
- Rebase after the pll struct changes.
v6:
- Properly make the unmap function based on encoders_post_disable()
with regarding to checks and iterators.
- Address checkpatch comment on "min = max = x()".

Spec describe all values in MHz. We handle our
clocks in KHz. This includes the best_dco_centrality that was
forgot in the same unity as spec. Consequently we couldn't
get a good divider for high frequenies. Hence HDMI 2.0 wasn't
working.
Spec tells 999999 for initial best_dco_centrality meaning the
max value in MHz.
Since we convert dco from MHz to KHz we also need to convert
this initial best_doc_centrality to 999999000 or 999999999
or even better, to the max that its variable allow.
This patch also replaces the use of "* KHz(1)" with the values
directly on KHz to avoid future confusion.
v2: Use U32_MAX instead of random 99999 as spec tells. (Ville).

Replace dig_port->port with encoder->port in the BXT DPLL selection.
We can do this because both the master encoder and the fake MST encoders
have the same encoder->port value, whereas using dig_port->port only
worked for the master encoder since the fake encoders were't derived
from intel_digital_port. This eliminates the DP MST special case.
Do this by hand because spatch is having problems with the control
flow due to the dig_port assignment happening in two different
branches.

On CNL we may need to bump up the system agent voltage not only due
to CDCLK but also when driving DDI port with a sufficiently high clock.
To that end start tracking the minimum acceptable voltage for each crtc.
We do the tracking via crtcs because we don't have any kind of encoder
state. Also there's no downside to doing it this way, and it matches how
we track cdclk requirements on account of pixel rate.
v2: Allow disabled crtcs to use the min voltage
Add IS_CNL check to intel_ddi_compute_min_voltage() since
we're using CNL specific values there
s/intel_compute_min_voltage/cnl_compute_min_voltage/ since
the function makes hw specific assumptions about the voltage
values
v3: Drop the test hack leftovers from skl_modeset_calc_cdclk()

- compute Cannonlake port clock programming
dividers P, Q, and K.
- compute PLL parameters for Cannonlake. These parameters

- find the register values to program wrpll for Cannonlake.
The reference clock can be either 19.2MHz or 24MHz.

Although CNL follows PLL initialization more like Skylake
than Broxton we have a completely different initialization
sequence and registers used.
One big difference from SKL is that CDCLK PLL is now
exclusive (ADPLL) and for DDIs and MIPI we need to use
DFGPLLs 0, 1 or 2.
v2: Accept all Ander's suggestions and fixes:
- Registers and bits names prefix
- Group pll functions
- bits masks fixes
- remove read and modify on cfgcr1
- fix cfgcr0 setup
v3: Set SSC_ENABLE for DP.
Fix HDMI_MODE cfgcr0.
Avoid touch cfgcr0 on DP.
Add missed else on dpll_mgr definition so we use cnl one, not hsw.
v3: Centra freq should be always set to default and change bits
definitions to (1 << 1) instead of (1<<1). (by Paulo)
v4: Rebased.

Along with GLK it was introduced the .is_lp and IS_GEN9_LP.
So, following the same simplification standard we can
put Skylake and Kabylake under the same bucket for most
of the things.
So let's add the IS_GEN9_BC for "Big Core" (non Atom based
platforms).
The i915_drv.c was let out of this patch on purpose
because that is really a decision per platform, just like
other cases where IS_KABYLAKE is different from IS_SKYLAKE.
v2: fix conflict with IS_LP and 3 new cases for this
big core bucket:
- intel_ddi.c: intel_ddi_get_link_dpll
- intel_fbc.c: find_compression_threshold
- i915_gem_gtt.c: gtt_write_workarounds
