intel/common/../systemagent: Add sa_get_mchbar_base api

Implement sa_get_mchbar_base api to get mchbar base address.
This api reads mchbar base address from pci config space if MCHBAR is
enabled and program MCHBAR base address and enable MCH BAR if MCHBAR is
not enabled. This api will be used in IOC driver for new SOC like
Meteor Lake.
