libipa: Add CameraSensorHelper for OV13858
Extend the CameraSensorHelper factory with support for an
OV13858 sensor as found in the Soraka Chromebook.
The datasheet states that low 7 bits are fraction bits, so the gain is
calculated as gainCode=128*gain.
According to the formula, it means m0=1 and c1=128.
m1 then has to be 0, and c0=0.
