In particular, we need to ensure all the necessary blocks are switched
to 64b mode (a5xx+) otherwise the high bits of the address of the BO to
snapshot state into will be ignored, resulting in:
*** gpu fault: ttbr0=0000000000000000 iova=0000000000012000 dir=READ
type=TRANSLATION source=CP (0,0,0,0)
platform 506a000.gmu: [drm:a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU
OOB set BOOT_SLUMBER: 0x0
Fixes: 4f776f4511c7 ("drm/msm/gpu: Convert the GPU show function to use the GPU
state")
