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.
