Subject: [PATCH v2 3/3] media: atomisp: Use max() macros

The max() macro produce nicer code and also fixes the following cocci
errors:

drivers/staging/media/atomisp/pci/sh_css_frac.h:40:17-18: WARNING opportunity for max()
drivers/staging/media/atomisp/pci/sh_css_frac.h:50:17-18: WARNING opportunity for max()
