media: i2c: imx219: Fix binning for RAW8 capture

Browse source

2x2 binning works fine for RAW10 capture, but for RAW8 1232p mode it
leads to corrupted frames [1][2].

Using the special 2x2 analog binning mode fixes the issue, but causes
artefacts for RAW10 1232p capture. So here we choose the binning mode
depending upon the frame format selected.

As both binning modes work fine for 480p RAW8 and RAW10 capture, it can
share the same code path as 1232p for selecting binning mode.
