Subject: amdgpu/drm: remove psp access on navi10 for sriov
Git-commit: 193cce34a105d5acb97e83bf7d2321b4c24be7b4
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Navi ASICs don't require to access through PSP to osssys registers.
This on SR-IOV configuration.
