msm: camera: ife: Program RDI clients in line based mode

Gralloc allocated buffers are aligned before calculating
stride, which can lead to corruption in frame based mode.
This change programs RDI clients in line based mode when
the output format is PLAIN_16 to prevent this. RDI clients
support only PLAIN128 packing format and this change also
enforces that.
