PMC driver has capability to get the IP information, idle mask values and
STB data from the PMFW. Extend this support to the platforms that belong
to family 1Ah model 60h series.

This is actually a fix for another commit in 6.11. Hans, Ilpo, can you
please take it in fixes?
Fixes: 426463d94d45d ("platform/x86/amd/pmc: Send OS_HINT command for

I'm not certain how this commit addresses the existing issue. Last
week, when I sent out commit 426463d94d45d, I tested the changes on my
test bed, and everything seemed to work fine.
If this new commit is indeed resolving an existing problem, I shall
amend the commit message to make it more meaningful.
Thanks,
Shyam

Hmm when I was talking to a colleague about it this morning s0i3 didn't
start working on this platform until this change, presumably because the
message IDs weren't properly configured without it.

For that, a proper justification is necessary in the commit message (but
I guess Shyam was going to improve that too while respinning given the
other replies).
