[PATCH] serial: Make uart_port's ioport "resource_size_t"

[Josh Boyer]

Recently uart_port's iobase was changed to be an 'unsigned
long' to avoid chopping off the upper 32-bits of the
address on 64-bit CPUs.  However, there are CPUs that are
32-bit but have a 64-bit address space.  This changes
iobase to be 'resource_size_t' to accommodate those types
of systems.  This also matches what is done for the mapbase
member of uart_port.
