serial: 8250_bcm2835aux: Use generic remapping code
On probe the bcm2835aux UART driver misreports the register base address
as 0x0:
ttyS0 at MMIO 0x0 (irq = 53, base_baud = 50000000) is a 16550
That's because the driver remaps the registers itself. Take advantage
of the generic remapping code in serial8250_request_std_resource() to
get a message with the correct address and to simplify the driver.
