libpayload: Jazz: Enable serial console

Ramstage should share some data with depthcharge and libpayload.
    But in case of Jazz we do not wish to share any buffer and just
    want to enable serial console and for that we ask UART's base
    address from config.

BUG=None
    BRANCH=None
    TEST=Saw prints over console from depthcharge
