intel/fsp_baytrail: Fix SMM/SMI
With SMM enabled the boot stopped while patching up global NVS in DSDT.
The cause is that both CPUs are assigned the same SMBASE address.
So update the "cpu_smm_do_relocation()" function so that each
CPU gets a different SMBASE address
Based on rmodule work that wasn't propagated to the FSP
version: commit 3eb8eb7eba55cdfd64c8d50181ea066526ff6485
