ipa: ipu3: awb: Use the line stride for the stats

The statistics buffer 'ipu3_uapi_awb_raw_buffer' stores the ImgU
calculation results in a buffer aligned horizontally to a multiple of 4
cells. The AWB loop should take care of it to add the proper offset
between lines and avoid any staircase effect.

It is no longer required to pass the grid configuration context to the
private functions called from process() which simplifies the code flow.
