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 Change-Id: I77cd27d3a4f207411a689b5be572b4406a03f16b Signed-off-by: Kayalvizhi Dhandapani <kayalvizhid@ami.com> Reviewed-on: http://review.coreboot.org/7026 Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Marc Jones <marc.jones@se-eng.com> Tested-by: build bot (Jenkins)
