The series adds mode-1 reset support to SMU v13.0.6 SOCs. For now, it's used as
the default reset method on dGPUs with SMU v13.0.6.  Presently, reset takes
longer than expected. Hence a method is added to check the bootloader status
after reset. It checks if bootloader has set mailbox ready bit which is an
indication that boot loader has completed initialization.

  drm/amdgpu: Unset baco dummy mode on nbio v7.9
  drm/amdgpu: Add bootloader status check
  drm/amdgpu: Add bootloader wait for PSP v13
  drm/amdgpu: Add SMU v13.0.6 default reset methods
