platform/x86/amd/pmc: Fix SMU command submission path on new AMD platform

Browse Source 
The commit 426463d94d ("platform/x86/amd/pmc: Send OS_HINT command for
new AMD platform") was introduced to enable sending mailbox commands to
PMFW on newer platforms. However, it was later discovered that the commit
did not configure the correct message port ID (i.e., S2D or PMC). Without
this configuration, all command submissions to PMFW are treated as
invalid, leading to command failures.

To address this issue, the CPU ID association for the new platform needs
to be added in amd_pmc_get_ip_info(). This ensures that the correct SMU
port IDs are selected.
