Subject: [PATCH 2/3] drm: kirin9xxx: Add additional color formats

This is against Mauro's tree here:
https://gitlab.freedesktop.org/mchehab_kernel/hikey-970/-/commits/master/

Add support for two color formats (ARGB and ABGR) needed for use
with drm_hwcomposer and AOSP.

NOTE: I see Red/Blue swapped colors with this (and yes I did try
the obvious swap of formats here, to no luck :), so I need to dig
more on whats different from the other driver on this.

But with these formats supported drm_hwcomposer no longer crashes
