media: staging: media: imx: imx7-media-csi: Fix list of supported formats

The list of supported formats comes from helpers shared with the i.MX6
IPUv3 and is incorrect in multiple regards:

- 10-, 12- and 14-bit Bayer formats are stored in memory as SBGGR10,
  SBGGR12 and SBGGR14 respectively (plus components permutations), not
  SBGGR16. Same thing for greyscale formats.
- 16-bit RAW formats are not supported by the hardware.

Fix the supported formats table.
