Split up output register functions

Browse Source 
The old code was writing registers more often than it needed to. TMDS
writes were triggered by changing the mode for an LVDS panel and RMX
writes were triggered by changing the mode for the second crtc. This
splits TMDS, LVDS, DAC and RMX calls into their own functions.

Also note that routing bits have been specified. R128_FP_SEL_CRTC2 and
R128_LVDS_SEL_CRTC2 are always unset to make the panels use the first
crtc. R128_DAC_CRT_SEL_CRTC2 is unset unless LVDS is already using the
first crtc.
