[PATCH v2 2/3] media: rkisp1: Make local immutable array variables static const

[Paul Elder]

From: Laurent Pinchart <laurent.pinchart at ideasonboard.com>

The max_widths and max_heights variables in rkisp1_try_fmt() are
immutable and don't need to be allocated on the stack every time the
function is called. Make them static.
