drm/amdgpu: Wait for bootloader after PSPv11 reset
Some PSPv11 SOCs take a longer time for PSP based mode-1 reset. Instead
of checking for C2PMSG_33 status, add the callback wait_for_bootloader.
Wait for bootloader to be back to steady state is already part of the
generic mode-1 reset flow. Increase the retry count for bootloader wait
and also fix the mask to prevent fake pass.
Fixes: 8345a71fc54b ("drm/amdgpu: Add more checks to PSP mailbox")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4531
