[PATCH v2 4/7] media: i2c: imx219: Fix colorspace info

[Jacopo Mondi <jacopo.mondi@xxxxxxxxxxxxxxxx>]

The IMX219 is a RAW sensor. Fix the colorspace configuration by
using V4L2_COLORSPACE_RAW and adjust the quantization and transfer
function values. Drop ycbcr_enc as it doesn't apply to RAW sensors.
