[PATCH 6/8] media: imx: imx7_media-csi: Add support for additional Bayer patterns

[Alexander Stein]

imx7_csi_configure() allows configuring these Bayer patterns when
starting a stream. So allow these in link_validate() as well.

I'm wondering if V4L2_PIX_FMT_SBGGR16 (and their variants) is correct in this
function. imx7_csi_configure() does not list MEDIA_BUS_FMT_Sxxxx16_1X16.
Also I can't find a proper a proper setting in CSI_CR18 of CSI Bridge in
IMX8M Mini RM for RAW16. The feature list names a  "16-bit data port for
Bayer data input", but is it actually supported? I do not know anything about
the MIPI CSI data formats though. Maybe someone else can clarify this.
