video: tegra: fb: Add interface to nvdps.
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.
