Use v4l2_i2c_subdev_set_name() to set the name of the smiapp driver's
sub-devices. There is no functional change.

v4l2_i2c_subdev_set_name() can be used to assign a name to a sub-device.
This way uniform names can be formed easily without having to resort to
things such as snprintf in drivers.

Currently 2-bytes and 3-bytes registers are read one byte at a time,
doing the needed shift & mask each time.
Replace all of this code by a unique helper function that calls
regmap_bulk_read(), which has two advantages:
- reads all the bytes in a unique I2C transaction
- simplifies code to read multibyte registers

Forcibly setting the subdev name to DRIVER_NAME (i.e. "IMX274") makes

Rearrange the imx274_start_<N> register tables to better match the
datasheet and slightly simplify code:
- collapes tables 1 and 2, they are applied one after each other and
together they implement the fixed part 1 of the startup procedure
in the datasheet
- while there, cleanup comments
- rename tables 3 and 4 -> 2 and 3, coherently with the datasheet

The UDS is currently restricted based on a partition size of 256 pixels.
Document the actual restrictions, but don't increase the implementation.

The function only consists of a single switch case block without a
default case. Unsupported control requests are indicated by the -EINVAL
return code trough the last return statement at the end of the function. So
exiting just the switch case block returns the -EINVAL error code but the
hue control is supported and a zero should be returned instead.
Replace the break by a 'return 0' to fix this behaviour.

Consumer devices are provided with a wide different range of types
supported by the same driver, allowing different configutations.
In order to make easier to setup media controller links, "taint"
pads with the signal type it carries.
While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries
is actually the same as the normal video output.
The difference happens at the video/VBI interface:
- for VBI, only the hidden lines are streamed;
- for video, the stream is usually cropped to hide the
vbi lines.
