platform/x86/amd/pmf: Replace magic table id with METRICS_TABLE_ID

Browse Source 
Add METRICS_TABLE_ID (7) and use it when requesting the metrics
transfer table instead of the hard-coded literal. This clarifies the
meaning of the argument to amd_pmf_send_cmd() and centralizes the table
ID definition for easier maintenance.
