[PATCH] tty: serial: msm: fix definition of msm_stop_dma

[ben.dooks@codethink.co.uk (Ben Dooks)]

The msm_stop_dma() is not exported from the driver, so make
it static to stop the following warning:

drivers/tty/serial/msm_serial.c:84:6: warning: symbol 'msm_stop_dma' was not declared. Should it be static?
