superio/fintek/*: Factor out generic romstage component

The romstage of Fintek Super I/O's is identical, leading to replication
    of essentially the same code prone to bitrot. Herein we consolidate the
    early pre-ram UART initialisation code into fintek/common, rather we
    leave the exceptions to be implemented under model/.

More precisely we provide a well documented version of early_serial.c
    under fintek/common and select by way of Kconfig as a generic romstage
    component to Super I/O support. We leave future Super I/O's the option
    to implement `non-standard` initialisation code should such a (unlikely)
    need araise. A primary advantage is that new support for romstage serial
    is now trival to add. We also provide some Kconfig documentation while
    here.
