David (Ming Qiang) Wu 0ef2803173 drm/amdgpu/vcn1: read back register after written 
V3: drop changes where readbacks have implemented. This patch set
    is to add readbacks only.

V2: use common register UVD_STATUS for readback (standard PCI MMIO
    behavior, i.e. readback post all writes to let the writes hit
    the hardware)
    add readback in ..._stop() for more coverage.

Similar to the changes made for VCN v4.0.5 where readback to post the
writes to avoid race with the doorbell, the addition of register
readback support in other VCN versions is intended to prevent potential
race conditions, even though such issues have not been observed yet.
This change ensures consistency across different VCN variants and helps
avoid similar issues. The overhead introduced is negligible.
