Subject: [PATCH AUTOSEL 6.7 08/88] drm/msm/a690: Fix reg values for a690

From: Danylo Piliaiev <dpiliaiev@...lia.com>

[ Upstream commit 07e6de738aa6f0e873463e9ca88bdb7081c4bfd4 ]

KGSL doesn't support a690 so all reg values were the same as
on a660. Now we know the values and they are different from the
windows driver.

This fixes hangs on D3D12 games and some CTS tests.
