Provide /sys/class/graphics/fb0/device/nvdps to change video mode
on-the-fly without resetting window layout like fb_set_var(). This
allows flicker free changes in refresh rate.
nvdps sysfs file takes an integer, and selects the closest matching mode
with the same or higher refresh rate. Reading the file displays the
current refresh rate.

Includes:
1.) Added basic DC sysfs objects.
2.) Sysfs objects and functions for smartdimmer settings.
3.) Register dump access for smartdimmer.
4.) Improvements to the behavior of smartdimmer (now updates
at the end of vblank instead of the beginning).
5.) Rename v_blank_complete to vblank_complete to keep in
same effective style as the rest of the code.
