ARM: dts: msm: Add GMU CX GenPD instance

Browse Source 
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.
