Subject: [PATCH v3 6/7, RFC] drm/panfrost: Add mt8183-mali compatible string

For testing only, the driver doesn't really work yet, AFAICT.

Signed-off-by: Nicolas Boichat <drinkcat@...omium.org>

v3:
 - Match mt8183-mali instead of bifrost, as we require special
   handling for the 2 regulators and 3 power domains.
