drm/etnaviv: fix power register offset on GC300

Browse source

[ Upstream commit 61a6920bb6 ]

Older GC300 revisions have their power registers at an offset of 0x200
rather than 0x100. Add new gpu_read_power and gpu_write_power functions
to encapsulate accesses to the power addresses and fix the addresses.
