radeon: insert 10ms sleep in dce5_crtc_load_lut
[ Upstream commit ec3d65082d7dabad6fa8f66a8ef166f2d522d6b2 ]

introduced for some people (but not all) in
commit b8e2b0199cc377617dc238f5106352c06dcd3fa2

drm/fb-helper: factor out pseudo-palette

10ms in a fairly slow modeset path feels like an acceptable form of
duct-tape, so maybe worth a shot and see what sticks.
