This patch to ensures that coreboot is performing LPC 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 lpc register lock down has been moved right after pci resource allocation is done, so that lpc registers can be lock down before calling post pci enumeration FSP NotifyPhase() API which is targeted to be done in BS_DEV_ENABLE-BS_ON_ENTRY. TEST=Ensure LPC register 0xDC bit 1 and 7 is set.
