atheros[uart]: pass only physical I/O mem address to 8250 driver
Pass only physical address to 8250 serial port driver and set flag to remap I/O memory inside the driver. Also fix AR5312 UART base address definition, which seems specified already mapped. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com> SVN-Revision: 41700
