ARM: SoC drivers for 6.6 

The main change this time is the introduction of the drivers/genpd
 subsystem that gets split out from drivers/soc to keep common
 functionality together. Ulf Hansson is taking over maintainership for
 these and is sending a separate pull request with the same commits,
 but they are in the soc drivers tree to avoid conflicts against other
 soc driver patches.
 
 The SCMI driver subsystem gets an update to version 3.2 of the
 specification. There are also updates to memory, reset and other firmware
 drivers.
 
 On the soc driver side, the updates are mostly cleanups across a number
 of Arm platforms. On driver for loongarch adds power management for DT
 based systems, another driver is for HiSilicon's Arm server chips with
 their HCCS system health interface.
 
 The remaining updates for the most part add support for additional
 hardware in existing drivers or contain minor cleanups. Most of these
 are for the Qualcomm Snapdragon platform.

contains read-only attributes exposing information about
a HCCS port. The N value in 'hccsN' indicates this port id.
The X in 'chipX' indicates the ID of the chip to which the
HCCS port belongs. For example, X ranges from to 'n - 1' if the
chip number on platform is n.
The Y in 'dieY' indicates the hardware id of the die to which
the hccs port belongs.
Note: type, lane_mode and enable are fixed attributes on running
platform.
The HCCS port have the following attributes:
============= ==== =============================================
type: (RO) port type (string), e.g. HCCS-v1 -> H32
lane_mode: (RO) the lane mode of this port (string), e.g. x8
enable: (RO) indicate if this port is enabled (bool).
cur_lane_num: (RO) current lane number of this port.
link_fsm: (RO) link finite state machine of this port.
lane_mask: (RO) current lane mask of this port, every bit
indicates a lane.
crc_err_cnt: (RO) CRC err count on this port.

The firmware running on the processor inside the RPM subsystem allows each
component in the system to vote for state of the system resources, such as
clocks, regulators and bus frequencies. It implements multiple separate
communication interfaces that are described in subnodes, e.g. SMD and MPM:

| | RPM firmware | | | |

The services provided by the firmware are only available after the firmware
has been loaded and the processor has been released from reset. Usually this
happens early in the boot process before the operating system is started.
