media: vsp1: Fix offset calculation for plane cropping
[ Upstream commit 5f25abec8f21b7527c1223a354d23c270befddb3 ] The vertical subsampling factor is currently not considered in the offset calculation for plane cropping done in rpf_configure_partition. This causes a distortion (shift of the color plane) when formats with the vsub factor larger than 1 are used (e.g. NV12, see vsp1_video_formats in vsp1_pipe.c). This commit considers vsub factor for all planes except plane 0 (luminance). Drop generalization of the offset calculation to reduce the binary size.
