serial: 8250_pxa: avoid autodetecting the port type
If we're unlucky enough that this drivers binds to a mrvl,mmp-uart device
on a MMP3, the port type gets detected as 16550A instead of XScale, and it
won't work. Other drivers that may bind to the same hardware are 8250_of
and, god forbid, serial_pxa.
Force the port type, we know it's a PORT_XSCALE.
