[PATCH 07/20] drm/amd/display: Fix disbling PSR slow response issue

[Stylon Wang]

From: Tom Chung <chiahsuan.ch...@amd.com>

[Why]
dmub_psr_get_state() return an invalid PSR state while disable
the PSR because convert_psr_state() doesn't recognize the state
that return from DMCUB.

[How]
Add a PSR state to make the dmub_psr_get_state() return a
correct PSR state.
