what changed:
1)provide new implementation interface for the rlcg access path
2)put SQ_CMD/SQ_IND_INDEX to GFX9 RLCG path to let debugfs's reg_op
function can access reg that need RLCG path help

now even debugfs's reg_op can used to dump wave.

<title>drm/amdgpu: Initialize SPM_VMID with 0xf (v2)</title>

SPM_VMID is a global resource, SPM access the video memory according to
SPM_VMID. The initial valude of SPM_VMID is 0 which is used by kernel.
That means UMD can overwrite the memory of VMID0 by enabling SPM, that
is really dangerous.

Initialize SPM_VMID with 0xf, it messes up other user mode process at
most.

v2: squash in indentation fix

Instead of putting toc into driver source code, the toc will
be part of psp_sos fw. Driver need to get and parse it from
psp fw
