SERIAL: 8250: Remove SERIAL_8250_AU1X00
Remove the SERIAL_8250_AU1X00 config symbol. Instead, use the MIPS_ALCHEMY
one which is always defined when building an Au1x00-based platform.

This one depends on a previous patch (which removes SOC_AU1X00 and changes
MACH_ALCHEMY) to apply cleanly (and then actually work), so I'd love for
this to go in via the mips tree.
