udlfb: Make sure to get correct endian keys from vendor descriptor

Browse Source 
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.
