[SERIAL] Remove base_baud default from 8250_pci

Since all boards specify base_baud, the code to default base_baud to
the architecture-defined BASE_BAUD is redundant.  Also, defaulting
to the architecture-defined BASE_BAUD is wrong since the UARTs on a
serial PCI card will be clocked at the same rate no matter what the
architecture of the host machine.
