Currently, there is a race condition in GenPD framework where
GPU CX GDSC can remain ON if both GMU and KGSL SMMU devices are
suspending in parallel and are voting on the same power domain.
Guidance from genpd team is to use a dedicated power domain for
CX GDSC voting.

GDSCs were modeled as regulators till now. However,
moving forward, GDSCs will be treated as power domains.
Consequently, replace references to ‘regulators’ with
‘power domains’ for the sun GPU.

SVS is the highest voltage corner for GMU. The lowest DDR BW
that puts CX at SVS corner is 1555 MHz. This DDR vote puts CX
at a corner high enough such that GMU can run at 650 MHz. This
is to get better GMU performance at no extra power cost.

For gen8 targets, frequency limiter violations are published
through cx_host_irq interrupt. Thus, add cx_host_irq for sun
GPU.
