Only one board uses the UPIO_DWAP iotype, and nothing uses
the UPIO_DWAP32 iotype. It seems much cleaner to handle the
DWAP quirk as a new port type, and move the serial_out
accessor into the platform code. If more platforms start
using the DWAP port, that function can be moved into a
common location.

Half of this patch appears to be unrelated work on HUB6

Both halves look right but did you accidentally fold two patches
together ?
