Patch: ATI Xilleon port 3/11 serial/8250 Set UART_CAP_FIFO in early_serial_setup

[David Daney <ddaney@avtrex.com>]

This is the third part of my Xilleon port.

I am sending the full set of patches to linux-mips@linux-mips.org
which is archived at: http://www.linux-mips.org/archives/

Only the patches that touch generic parts of the kernel are coming
here.

The Xilleon's (32bit MIPS SOC) serial ports do not work right if the
fifo is not enabled.  This prevented early serial support from
working.

The fix is to set UART_CAP_FIFO in early_serial_setup iff the hardware
says it supports it.

Patch against 2.6.14-rc2 from linux-mips.org

Signed-off-by: David Daney <ddaney@avtrex.com>

Set UART_CAP_FIFO in early_serial_setup() if the port has that
capability.  Needed by xilleon port.
