platform/x86:intel/pmc: Improve function to show substate header
Refactor pmc_core_substate_req_header_show() to accept a new argument. This is a preparation patch to introduce a new way to show Low Power Mode substate requirement data for platforms starting from Panther Lake. Increased the size for the name column as the Low Power Mode requirement register name is longer in newer platforms.
