ipa: ipu3: Introduce a modular tone mapping algorithm
Introduce a new algorithm to manage the tone mapping handling of the
IPU3.
The initial algorithm is chosen to configure the gamma contrast curve
which moves the implementation out of AWB for simplicity. As it is
initialised with a default gamma value of 1.1, there is no need to use
the default table at initialisation anymore.
This demonstrates the way to use process() call when the EventStatReady
comes in. The function calculates the LUT in the context of a frame, and
when prepare() is called, the parameters are filled with the updated
values.
AGC is modified to take the new process interface into account.
