Subject: drm/cirrus: correct register values for 16bpp
From: Takashi Iwai <tiwai@xxxxxxx>
commit 2510538fa000dd13a3e57b79bf073ffb1748976c upstream.
When the mode is set with 16bpp on QEMU, the output gets totally broken.
The culprit is the bogus register values set for 16bpp, which was likely
copied from from a wrong place.
