soc/intel/skylake: Move DMI lock down config after resource allocation
This patch to ensures that coreboot is performing DMI
registers lockdown after PCI enumeration is done.
This requirements are intended to support platform security
guideline where all required chipset registers are expected
to be in lock down stage before launching any 3rd party
code as in option rom etc.
coreboot has to change its execution order to meet those
requirements. Hence BIOS Interface lock down through Sideband
access has been moved right after pci resource allocation is done,
so that BILD lock down is getting executed along with LPC and SPI
BIOS interface lockdown settings before calling post pci
enumeration FSP NotifyPhase() API which is targeted to
be done in BS_DEV_ENABLE-BS_ON_ENTRY.
TEST=Ensure DMI register offset 0x274c bit 0 is set.
