	Remove any hard-coded assumptions about the target hardware platform from the autofocus algorithm. Instead, use the "target" string provided by the camera tuning config and generalised statistics structures to determing parameters such as grid and region sizes. Additionally, PDAF statistics are represented by a generalised region statistics structure to be device agnostic. These changes also require the autofocus algorithm to initialise region weights on the first frame's prepare()/process() call rather than during initialisation.

2023-01-30	ipa: raspberrypi: Add autofocus algorithm interface headers	Nick Hollinghurst
	Add a new AfAlgorithm class that defines the interface for the Raspberry Pi autofocus algorithm. Add an AfStatus structure that returns the results of the autofocus algorithm back to the IPA. Add a structure for PDAF statistics provided by supported sensors for use with an autofocus algorithm. This structure is currently based on the IMX708's PDAF "Type 1" statistics.
