[PATCH 3/5] video: ipu-fb: mark internally used functions as static

[Lucas Stach]

Fixes symbol clashes with the IPUv3 driver:
In function `ipu_ch_param_write_field':
drivers/video/imx-ipu-v3/ipu-common.c:103: multiple definition of `ipu_ch_param_write_field'
drivers/video/imx-ipu-fb.c:359: first defined here

In function `ipu_cpmem_set_format_rgb':
drivers/video/imx-ipu-v3/ipu-common.c:155: multiple definition of `ipu_cpmem_set_format_rgb'
drivers/video/imx-ipu-fb.c:504: first defined here
