e34ebe008f ipa: ipu3: agc: Rewrite and simplify the brightness loop 
Now that we know how the AWB statistics are formatted, use a simplified
loop in processBrightness() to parse the green values and get the
histogram.

b3befe2ef0 ipa: ipu3: agc: remove local storage of the grid 
The IPASessionConfiguration now has the grid configuration stored. Use
it at process() call in AGC and pass it as a reference to the private
functions when needed.

93802f600c ipa: ipu3: Move IPU3 agc into algorithms 
Now that the interface is properly used by the AGC class, move it into
ipa::ipu3::algorithms and let the loops do the calls.
As we need to exchange the exposure_ and gain_ by passing them through the
FrameContext, use the calculated values in setControls() function to
ease the reading.
