media: ipu3-imgu: Refactor bytesperpixel calculation
Move the calculation to an inline function, to it can be used by other parts of the driver. Signed-off-by: Ricardo Ribalda <ribalda@chromium.org> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
