Such fallback string is present in the 'soc_camera' version of the R-Car VIN
driver, so need to add it here as well...

The media bus format reported by the adv7180 is wrong. Steve Longerbeam
posted a patch which changed the format to UYVY8_2X8 with the commit
message:
Change the media bus format from YUYV8_2X8 to UYVY8_2X8. Colors
now look correct when capturing with the i.mx6 backend. The other
option is to set the SWPC bit in register 0x27 to swap the Cr and Cb
output samples.
The rcar-vin driver was developed and tested with the adv7180 and
therefor suffers from the same issue, looking for the wrong media bus
format. The two errors corrected each other.
This patch takes Steve's patch and merge it with a fix for rcar-vin
driver. The rcar-vin driver is used used in together with the adv7180
och Koelsch and this ensures it will not break while fixing the adv7180
issue. I checked wit Steve and he was fine with me merging the patches.

The primary reason for this change is to prepare for Gen3 support where
there will be more then one possible video source. Each source will have
its own media bus format and code, so it needs to be moved from the per
device structure to a structure used to represent an individual
connection to a video source.

The original drivers code to find a subdevice by looking in the DT grpah
and how the callbacks to the v4l2 async bind framework where poorly
written. The most obvious example of badness was the duplication of data
in the struct rvin_graph_entity.
This patch removes the data duplication, simplifies the parsing of the
DT graph and add checks to the v4l2 callbacks.

When Gen3 support is added to the driver more then one possible video
source entity will be possible. Knowing that the name entity is a bad
one, rename it to digital since it will deal with the digital input
source.
