drivers/video: fsl-diu-fb: add support for set_gamma ioctls
The MPC5121 BSP comes with a gamma_set utility that initializes the gamma table via an ioctl. Unfortunately, the ioctl number that utility uses is defined improperly, but we can still support it. Signed-off-by: Timur Tabi <timur@freescale.com>
