Subject: [PATCH] Revert "drm/udl: Add ARGB8888 as a format"

This reverts commit 95bf25bb9ed5dedb7fb39f76489f7d6843ab0475.

Apparently there was a previous discussion about emulation of formats
and it was decided XRGB8888 was the only format to support for legacy
userspace [1]. Remove ARGB8888. Userspace needs to be fixed to accept
XRGB8888.
