The main purpose of this commit is to make consecutive patches easier to
read. This is achieved with the following changes.
- Rename the variable 'entity' in struct rvin_dev to 'digital'. When we
add Gen3 support later this will only deal with the digital input
source.
- Rename all functions dealing with the v4l2 async framework and DT
parsing for the digital input from rvin_graph_* to rvin_digital_*.
- Reduce indentation in rvin_s_dv_timings() and use 'ret' instead of
'err' for return value variable as used in the rest of the driver.
- Order enum chip_id in chronological order.
- Fix indentation errors in rcar-v4l2.c which for some reason had bad
indentations at some locations.
