Add support for UPIO_MEM32BE in addition to UPIO_MEM32.
dw8250_serial_out32() extra functionality that is not part of
the 8250 core driver was moved to new function called
dw8250_check_LCR().

For big endian we use 2 new accessors similar to little endian,
called dw8250_serial_out32be() and dw8250_serial_in32be().
Both little and big endian accessors use dw8250_check_LCR()
for their dw8250_serial_out32{,be}().

In addition I added another 2 accessors inside private_data field of
uart_port. This second level accessors are set during probe in
private_data field of uart_port. Now any direct call to readl/writel
is replaced with those accessors which are endianness aware.

Last issue:
readl() for UCV and CPR will not work for port type UPIO_MEM32BE.
Instead we use the serial_in32() accessor which is initialized
properly according to endianness.

Can you please fix the warnings as pointed out by the kbuild testing and
resend this?
