drm/amdgpu: Check for valid number of registers to read
[ Upstream commit 73d8e6c7b841d9bf298c8928f228fb433676635c ]
Do not try to allocate any amount of memory requested by the user.
Instead limit it to 128 registers. Actually the longest series of
consecutive allowed registers are 48, mmGB_TILE_MODE0-31 and
mmGB_MACROTILE_MODE0-15 (0x2644-0x2673).
