[PATCH] drm/panfrost: add Mali-G68 support

[Markuss Broks via B4 Relay <devnull+markuss.broks.gmail.com@kernel.org>]

From: Markuss Broks <markuss.broks@gmail.com>

Add the features, issues, and ID for Mali-G68, a first-generation
(v9) Valhall GPU.
Tested on Exynos8835: the GPU reports GPU_ID 0x9204 (G68 r1p1).
