media: staging: rkisp1: add a helper function to enumerate supported mbus formats on capture

Browse source

Add a function 'rkisp1_cap_enum_mbus_codes' that receive
a pointer to 'v4l2_subdev_mbus_code_enum' and returns the
next supported mbus format of the capture. The function
assumes that pixel formats with identical 'mbus' are grouped
together in the hardcoded arrays, therefore the order of the
entries in the array 'rkisp1_sp_fmts' are adjusted.
This function is a helper for the media bus enumeration of
the source pad of the resizer entity.
