ea6bead7eb gpu: ipu-v3: Fix CSI data format for 16-bit media bus formats 
The CSI data format was being programmed incorrectly for the
1x16 media bus formats. The CSI data format for 16-bit must
be bayer/generic (CSI_SENS_CONF_DATA_FMT_BAYER).

6dd0d0e1ae gpu: ipu-v3: ipu-csi: bool test doesn't need a comparison to false 
Bool initializations should use true and false. Bool tests don't need
comparisons. Based on contributions from Joe Perches, Rusty Russell
and Bruce W Allan.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/boolinit.cocci.

3e47608f2d [media] gpu: ipu-v3: Make use of media_bus_format enum 
In order to have subsytem agnostic media bus format definitions we've
moved media bus definition to include/uapi/linux/media-bus-format.h and
prefixed enum values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.

Reference new definitions in the ipu-v3 driver.
