At present, various parts of the serial code use unsigned long to
define resource addresses.  This is a problem, because some 32-bit
platforms have physical addresses larger than 32-bits, and have mmio
serial uarts located above the 4GB point.

This patch changes the type of mapbase in both struct uart_port and
struct plat_serial8250_port to resource_size_t, which can be
configured to be 64 bits on such platforms.  The mapbase in
serial_struct can't safely be changed, because that structure is user
visible.
