Lijo Lazar 5251c83532 drm/amdgpu: Match against exact bootloader status
[ Upstream commit d3de41ee5febe5c2d9989fe9810bce2bb54a3a8e ]

On PSP v13.x ASICs, boot loader will set only the MSB to 1 and clear the
least significant bits for any command submission. Hence match against
the exact register value, otherwise a register value of all 0xFFs also
could falsely indicate that boot loader is ready. Also, from PSP v13.0.6
and newer, bits[7:0] will be used to indicate command error status.
