On the lite sku where GPU Fmax is 550Mhz, voting for a slightly higher
bandwidth at the highest gpu opp helps to improve "Manhattan offscreen"
score by 10%. Update the gpu opp table such that this is applicable only
on SKUs which has 550Mhz as GPU Fmax.

Some clients like adreno gpu driver would like to ensure that its gdsc
is collapsed at hardware during a gpu reset sequence. This is because it
has a votable gdsc which could be ON due to a vote from another subsystem
like tz, hyp etc or due to an internal hardware signal. To allow
this, gpucc dr
