[PATCH 06/13] drm/amdgpu: VCN 5_0_2 disable VCN_RRMT

From: Sonny Jiang <[email protected]>

When RRMT is enabled, VCN firmware's register access is remapped so
that VCN instances on different dies (VCN0/1 on MID0, VCN2/3 on MID1)
require different target addresses for the same logical register.

Remove the RRMT capability detection so the driver always assumes RRMT
is disabled, using local-die SMN addresses for all instances.
