udlfb: Make sure to get correct endian keys from vendor descriptor
The driver was not using le16_to_cpu when reading keys from the vendor descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not being parsed on big-endian systems. This would result in a blank screen on big-endian CPUs where the DL chips's max mode was smaller than the monitor's native mode.
