ramdisk: kill brightness at boot
mdss: implement panel color control

Adapted and modified work by CM-10.2, morfic and ktoonsez
- what a pain this was to make it work on hlte

    Creates a syfs interface here:
	/sys/class/lcd/panel/panel_colors

    Will accept 0-4 for parameters:
      0 - Cold (more blues)
      1 - Cool
      2 - Normal (stock colors)
      3 - Warm
      4 - Hot (more reds)
ramdisk: read panel color at boot
ramdisk: lkconfig - just two options for now
ramdisk: add permissions for panel color temp sysfs interfaces
Revert "mdss:set brightness to min_bl if brightness is less than min_bl."

This reverts commit f0695993449d4398fdee7195fb0ba38259ca6f81.

* this somehow raises minimum brightness - investigate later, or
don't mess with stuff you don't understand 100%
Revert "msm: mdss: maintain backlight-related variables in mfd structure"

This reverts commit f4dbd5ec1d591d1b7660f03d56f53029f434430e.
