serial: Make uart_port's ioport "unsigned long".
Otherwise the top 32-bits of the resource value get chopped off on 64-bit systems, and the resulting I/O accesses go to random places. Thanks to testing and debugging by Josip Rodin, which helped track this down. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
