drm/msm/a6xx: Limit GXPD votes to recovery in A8x

In A8x GPUs, the GX GDSC is moved to a separate block called GXCLKCTL
which is under the GX power domain. Due to the way the support for this
block is implemented in its driver, pm_runtime votes result in a vote on
GX/GMxC/MxC rails from the APPS RSC. This is against the Adreno
architecture which require GMU to be the sole voter of these collapsible
rails on behalf of GPU, except during the GPU/GMU recovery.

To align with this architectural requirement and to realize the power
benefits of the IFPC feature, remove the GXPD votes during gmu resume
and suspend. And during the recovery sequence, enable/disable the GXPD
along with the 'synced_poweroff' genpd hint to force collapse this GDSC.
