soc/intel/xeon_sp: Remove PAM lock and unlock operations

unlock_pam_regions routes Programmable Attribute Map (PAM) access
to DRAM. lock_pam0123 locks the setting before leaving coreboot.
In some SoCs, the FSP will by-default apply such settings
and hence bootloader setting is not needed.

Move unlock_pam_regions and lock_pam0123 from common boot steps to
SoC specific boot steps.
