ipa: camera_sensor_helper: Add AR0521 support
Add support for OnSemi AR0521 5Mpx image sensor to libipa.
The sensor analogue gain is implemented as a coarse and a fine factor,
with the coarse gain being a power of two and the fine gain being a
value in the [1.0, 2.0[ range. The mapping between gain codes and gain
values is tabulated in the datasheet, and the table values are very
close but not identical to the mathematical model. Compute the gain
using the model to keep the code shorter, if this causes precision
issues the calculation could be replaced with a table.
