Arm SCMI updates for v6.7

Main additions this time include:

1. SCMI v3.2 clock configuration support:
   This helps to retrieve the enabled state of a clock as well as allow
   to set OEM specific clock configurations.

2. Support for generic performance scaling(DVFS):
   The current SCMI DVFS support is limited to the CPUs in the kernel.
   This extension enables it to used for all kind of devices and not
   only for the CPUs. It updates the SCMI cpufreq to utilize the power
   domain bindings. It also adds a more generic SCMI performance domain
   based on the genpd framework that as be used for all the non-CPU
   devices.

3. Extend the generic performance scaling(DVFS) support for firmware
   driver OPPs:
   Consumer drivers for devices that are attached to the SCMI performance
   domain can't make use of the current OPP library to scale performance
   as the OPPs are firmware driven and often obtained from the firmware
   rather than the device tree. These changes extend the generic OPP
   and genpd PM domain frameworks to identify and utilise these firmware
   driven OPPs.

4. SCMI v3.2 clock parent support:
   This enables the support for discovering and changing parent clocks
   and extending the SCMI clk driver to use the same.

5. Qualcom SMC/HVC transport support:
   The Qualcomm virtual platforms require capability id in the hypervisor
   call to identify which doorbell to assert when supporting multiple
   SMC/HVC based SCMI transport channels. Extra parameter is added to
   support the same and the same is obtained at the fixed address in the
   shared memory which is initialised by the firmware.

6. Move the existing SCMI power domain driver under drivers/pmdomain

Apart from the above main changes, it also include couple of minor fixes
and cosmetic reworks.
