arm64: provide early SoC initialization
Some of the SoC's need an early hook to configure certain registers. One example of this is on t132 where ramstage is the first thing being ran on the arm64 core and it is the only entity that can configure certain registers required for the rest of ramstage. Therefore, provide the opportunity for the SoC to implement such requirements. BUG=chrome-os-partner:30572 BRANCH=None TEST=Built and ran through coreboot.
