drm/amd/display: use udelay rather than fsleep
[ Upstream commit 1d66c3f2b8c0b5c51f3f4fe29b362c9851190c5a ]
This function can be called from an atomic context so we can't use
fsleep().
Fixes: 01f60348d8fb ("drm/amd/display: Fix 'failed to blank crtc!'")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4549
