platform/x86/amd/pmc: Add STB support for AMD Desktop variants

Previously, AMD's Ryzen Desktop SoCs did not include support for STB.
However, to accommodate this recent change, PMFW has implemented a new
message port pair mechanism for handling messages, arguments, and
responses, specifically designed for distinguishing from Mobile SoCs.
Therefore, it is necessary to update the driver to properly handle this
incoming change.

Add a new function amd_stb_update_args() to simply the arguments that
needs to be passed between S2D supported Mobile SoCs vs Desktop SoCs.
