Update vblank value while changing mode Add support to handle multiple link frequencies. Add dummy ctrl cases for pixel_rate and link frequency to avoid error while changing the modes dynamically. Update default link frequency from device tree max link frequency value. Update init_cfg() function to update the link frequency menu_skip_mask value.
