[Libdlo] UDLFB: Make sure to get correct endian keys from vendor descriptor

[Ben Collins]

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 left udlfb most certainly
broken on low level chips as the driver allows modes that are too
high for the chip by default.
