[U-Boot] videomodes: unify the two videomode formats

[Jeroen Hofstee]

Hello,

Currently there are two distinct implementation in videomodes.c.

1) video_get_params with parses videomode like:
video=ctfb:x:800,xv:1280,y:600,yv:1024,depth:16,mode:0,pclk:25000,
       le:56,ri:48,up:26,lo:5,hs:152,vs:2,sync:0,vmode:0,accel:0

2) video_get_video_mode which parses video-mode like:
video-mode=fslfb:1280x1024-32 at 60,monitor=dvi and accepts default
VESA modes.

For a LCD typically option 1 is needed, for DVI option 2 is allot nicer. 
I am
therefore tempted to merge both version in a backwards compatible
manner so e.g. on a board with both options, option 1 can be used to
fiddle around with LCD timing and option 2 when using DVI.

Any objections against such a change?

Regards,
Jeroen
