soc/intel/common/systemagent_server: Add server platform system agent

Intel server process has a different system agent design, it has some
differences with client platform such as (1) no BDSM and BGSM
registers; (2) different alignment size and bit fields in TOLUD,
TOUUD and TSEG registers. Thus this patch adds a new common block for
server platform system agent.
