[PATCH AUTOSEL 5.4 41/73] drm/amd/display: update soc bb for nv14

[Sasha Levin]

From: Martin Leung <martin.leung@amd.com>

[ Upstream commit d5349775c1726ce997b8eb4982cd85a01f1c8b42 ]

[why]
nv14 previously inherited soc bb from generic dcn 2, did not match
watermark values according to memory team

[how]
add nv14 specific soc bb: copy nv2 generic that it was
using from before, but changed num channels to 8

[PATCH AUTOSEL 5.4 42/73] drm/amdgpu: correct ROM_INDEX/DATA offset for VEGA20

[Sasha Levin]

From: Hawking Zhang <Hawking.Zhang@amd.com>

[ Upstream commit f1c2cd3f8fb959123a9beba18c0e8112dcb2e137 ]

The ROMC_INDEX/DATA offset was changed to e4/e5 since
from smuio_v11 (vega20/arcturus).
