drm/amd/display: Don't use fsleep for PSR exit waits on dmub replay

Browse source

[ Upstream commit b5236da757 ]

[Why]
These functions can be called from high IRQ levels and the OS will hang
if it tries to use a usleep_highres or a msleep.

[How]
Replace the flseep with a udelay for dmub_replay_enable.
