soc/intel/alderlake: Add support to update descriptor at runtime

On nereid, we need to update the descriptor based on fw_config (see
the following patch), so add support to update the descriptor at
runtime. This is a temporary workaround while we find a better solution.

This is basically adding back the configure_pmc_descriptor() function
removed in CB:63339, just making it generic.

BUG=b:226848617
TEST=With the following patch, Type-C and HDMI work on nereid.
