drm/udl: Add ARGB8888 as a format

Browse Source 
Even though the UDL driver converts to RGB565 internally (see
pixel32_to_be16() in udl_transfer.c), it advertises XRGB8888 for
compatibility. Let's add ARGB8888 to that list.

This makes UDL devices work on ChromeOS again after commit
c91acda3a380 ("drm/gem: Check for valid formats"). Prior to that
commit things were "working" because we'd silently treat the ARGB8888
that ChromeOS wanted as XRGB8888.

Fixes: c91acda3a380 ("drm/gem: Check for valid formats")
