ipa: raspberrypi: Add hardware configuration to the controller
Add a new Controller::HardwareConfig structure that captures the
hardware statistics grid/histogram sizes and pipeline widths. This
ensures there is a single centralised places for these parameters.
Add a getHardwareConfig() helper function to retrieve these values for a
given hardware target.
Update the statistics populating routine in the IPA to use the values
from this structure instead of the hardcoded numbers.
