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.
