[WHY]
for sriov odd# vf will modify vcn0 engine ip revision(due to multimedia bandwidth feature),
which will be mismatched with original vcn0 revision

[HOW]
add new version check for vcn0 disabled revision(3, 0, 192), typically modified under
sriov mode

Allow us to query instances versions more cleanly.

Instancing support is not consistent unfortunately. SDMA is a
good example.  Sienna cichlid has 4 total SDMA instances, each
enumerated separately (HWIDs 42, 43, 68, 69).  Arcturus has 8
total SDMA instances, but they are enumerated as multiple
instances of the same HWIDs (4x HWID 42, 4x HWID 43).  UMC
is another example.  On most chips there are multiple
instances with the same HWID.  This allows us to support both
forms.

v2: rebase
v3: clarify instancing support

In the past, we use MMSCH to determine whether a VCN is enabled or not.
This is not reliable since after a FLR, MMSCH may report junk data.

It is better to use IP discovery data.
