[PATCH -resend 3/6] drm/cirrus: Correct register values for 16bpp

[Jiri Slaby <jslaby@suse.cz>]

From: Takashi Iwai <tiwai@suse.de>

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.
