Get Parameters for the video mode:

2 diferent ways are possible:
"videomode=301" - 301 is a hexadecimal number describing the VESA
mode. Following modes are implemented:

"videomode=bootargs"
- the parameters are parsed from the bootargs.
The format is "NAME:VALUE,NAME:VALUE" etc.
Ex.:
"bootargs=video=ctfb:x:800,y:600,depth:16,pclk:25000"
Parameters not included in the list will be taken from
the default mode, which is one of the following:
mode:0 640x480x24
mode:1 800x600x16
mode:2 1024x768x8
mode:3 960x720x24
mode:4 1152x864x16
if "mode" is not provided within the parameter list,
mode:0 is assumed.
Following parameters are supported:
x xres = visible resolution horizontal
y yres = visible resolution vertical
pclk pixelclocks in pico sec
le left_marging time from sync to picture in pixelclocks
ri right_marging time from picture to sync in pixelclocks
up upper_margin time from sync to picture
lo lower_margin
hs hsync_len length of horizontal sync
vs vsync_len length of vertical sync
sync see FB_SYNC_*
vmode see FB_VMODE_*
depth Color depth in bits per pixel
All other parameters in the variable bootargs are ignored.
It is also possible to set the parameters direct in the
variable "videomode", or in another variable i.e.
"myvideo" and setting the variable "videomode=myvideo"..
