amd_hsmp: Add HSMP protocol version 5 messages

HSMP protocol version 5 is supported on AMD family 19h model 10h
EPYC processors. This version brings new features such as
-- DIMM statistics
-- Bandwidth for IO and xGMI links
-- Monitor socket and core frequency limits
-- Configure power efficiency modes, DF pstate range etc
