The vast majority of shared RCGs were not marked as such. Fix it.

The PCIe GDSCs can be shared with other masters and should use the APCS
collapse-vote register when updating the power state.
This is specifically also needed to be able to disable power domains
that have been enabled by boot firmware using the vote register.
Following other recent Qualcomm platforms, describe this register and
the corresponding mask for the PCIe (and _phy) GDSCs.

The PCIe GDSCs on most Qualcomm platforms expect the OS to always
consider collapse requests as successful. This also concerns SM8550.
Add the VOTABLE flag to the GDSCs in question to comply with these
expectations.

All of the 8550's GCC GDSCs can and should use the retain registers so
as not to lose their state when entering lower power modes.

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.

Change several entries of parent_data to use parent_hws instead, which
results in slightly more ovbious code.

Add Global Clock controller (GCC) driver for SM8550 SoC,
which includes the gcc resets and gdsc.
This patch is based on an initial downstream driver.
