[PATCH][next] spi: pxa2xx: make function pxa2xx_spi_transfer_one static

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

The function pxa2xx_spi_transfer_one is local to the source and
do not need to be in global scope, so make it static.

Cleans up sparse warning:
drivers/spi/spi-pxa2xx.c:914:5: warning: symbol 'pxa2xx_spi_transfer_one'
was not declared. Should it be static?
