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.
TEST=Built and ran through coreboot.
