Arm SCMI updates for v6.6
The main addition this time is the support for SCMI v3.2 perf level
indexing mode. SCMI v3.2 adds support for hardware which works on
performance indices, instead of levels. Certain platforms use indices
to identify performance levels. Level Indexing Mode is used to describe
such platform behavior. All commands which utilize performance level
as a parameter need to specify the corresponding level index instead of
the performance level when Level Indexing Mode is used.
While at it, these changes also include hardening of all the internal
accesses to the performance domain information.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

SCMI v3.2 adds PERF protocol support to optionally define performance
domains that cannot be represented on a linear scale; the platform firmware
can declare the performance levels of a domain as being 'level indexed' and
provide an indicative frequency associated to each of those levels, with
such indexes not required anymore to be contiguous nor to satisfy any
linear-scaling constraint: when level-indexing is available for a domain,
the platform will expect to deal with SCMI requests using indexes instead
of performance levels for that domain.
Add level-indexing mode support to the PERF protocol implementation while
maintaining unchanged the protocol operations interface exposed by PERF;
all the required mapping from performamce levels/frequencies to the
corresponding level indexes is carried out transparently by the core PERF
protocol support: as a consequence no change is either required in any
SCMI driver using the PERF protocol, even when using level indexing.

Create the new genpd subsystem and start moving providers
There are currently ~60 users of the genpd provider interface, which
implementations are sprinkled across various subsystems. To help out with
maintenance and to gain a bit better control, this creates a new subsystem
(drivers/genpd) and moves some of the soc/platform specific providers in
here.
Added dt-binding documentation for Versal NET platforms.
Versal Net is a new AMD/Xilinx SoC.
The SoC and its architecture is based on the Versal ACAP device.
The Versal Net device includes more security features in the
platform management controller (PMC) and increases the number
of CPUs in the application processing unit (APU) and the
real-time processing unit (RPU).

Two build regressions came up that I added fixes for
* drivers/genpd:
genpd: move owl-sps-helper.c from drivers/soc
soc: starfive: remove stale Makefile entry
Moving only one of the two files in drivers/soc/actions to drivers/genpd
caused a link failure in allmodconfig, as drivers/genpd is entered
for compile testing, but drivers/soc/actions accidentally got skipped:
x86_64-linux-gnu-ld: vmlinux.o: in function `owl_sps_set_power':
owl-sps.c:(.text+0x16e259d): undefined reference to `owl_sps_set_pg'
Move the other one as well to allow build testing to work correctly.
