omapfb: add support for rotation on the Blizzard LCD ctrl
The LCD controller (EPSON S1D13744) supports rotation (0, 90, 180 and 270
degrees) on hardware just setting the bits 0 and 1 of 0x28 register (LCD
Panel Configuration Register). Now it is possible to use this caps only
setting the angle degree on var rotate of fb_var_screeninfo using the
FBIOPUT_VSCREENINFO ioctl.
