mlxsw: Add support for new multipath hash policies
This patchset adds support for two new multipath hash policies in mlxsw.
Patch #1 emits net events whenever the
net.ipv{4,6}.fib_multipath_hash_fields sysctls are changed. This allows
listeners to react to changes in the packet fields used for the
computation of the multipath hash.
Patches #2-#3 refactor the code in mlxsw that is responsible for the
configuration of the multipath hash, so that it will be easier to extend
for the two new policies.
Patch #4 adds the register fields required to support the new policies.
Patch #5-#7 add support for inner layer 3 and custom multipath hash
policies.
Tested using following forwarding selftests:
* custom_multipath_hash.sh
* gre_custom_multipath_hash.sh
* gre_inner_v4_multipath.sh
* gre_inner_v6_multipath.sh
====================
When this policy is set, only enable the packet fields that were enabled
by user space for multipath hash computation.

When this policy is set, the kernel uses the inner layer 3 fields for
multipath hash computation and falls back to the outer fields if no
encapsulation was encountered. This behavior is most likely influenced
by the behavior of the flow dissector, which is used for the packet
dissection.
The Spectrum ASIC, however, cannot fallback to outer fields if inner
fields are not available. This should not result in a discrepancy from
the software data path because if several flows have matching inner
fields, they will tend to have matching outer fields as well.
Therefore, implement this policy by enabling both outer and inner layer
3 fields for the multipath hash computation.

Currently, the multipath hash configuration is written directly to the
register payload. While this is OK for the two currently supported
policies, it is going to be hard to follow when more policies and more
packet fields are added.
Instead, set the required headers and fields in a bitmap and then dump
it to the register payload.

The code was written when only two multipath hash policies were present,
so the if statement was sufficient. The next patch and future patches
are going to add support for more policies, so move to a switch
statement.

In-kernel notifications are already sent when the multipath hash policy
itself changes, but not when the multipath hash fields change.
Add these notifications, so that interested listeners (e.g., switch ASIC
drivers) could perform the necessary configuration.

S3FWRN5 depends on a clock input ("XI" pin) to function properly.
Depending on the hardware configuration this could be an always-on
oscillator or some external clock that must be explicitly enabled.
So far we assumed that the clock is always-on.
Make the driver request an (optional) clock from the device tree
and make sure the clock is running before starting S3FWRN5.
Note: S3FWRN5 asserts "GPIO2" whenever it needs the clock input to
function correctly. On some hardware configurations, GPIO2 is
connected directly to an input pin of the external clock provider
(e.g. the main PMIC of the SoC). In that case, it can automatically
AND the clock enable bit and clock request from S3FWRN5 so that
the clock is actually only enabled when needed.
It is also conceivable that on some other hardware configuration
S3FWRN5's GPIO2 might be connected as a regular GPIO input
of the SoC. In that case, follow-up patches could extend the
driver to request the GPIO, set up an interrupt and only enable
the clock when requested by S3FWRN5.

Similar to the way in which of_mdiobus_register() has a fallback to the
non-DT based mdiobus_register() when CONFIG_OF is not set, we can create
a shim for the device-managed devm_of_mdiobus_register() which calls
devm_mdiobus_register() and discards the struct device_node *.
In particular, this solves a build issue with the qca8k DSA driver which
uses devm_of_mdiobus_register and can be compiled without CONFIG_OF.
