3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mans Rullgard <mans@mansr.com>

commit 3c5a0357fdb3a9116a48dbdb0abb91fd23fbff80 upstream.

This adds an entry to the uart_config table for PORT_RT2880
enabling rx/tx FIFOs.  The UART is actually a Palmchip BK-3103
which is found in several devices from Alchemy/RMI, Ralink, and
Sigma Designs.
