ipa: rpi: agc: Implementation of multi-channel AGC
The switchMode, prepare and process methods are updated to implement
multi-channel AGC correctly:
* switchMode now invokes switchMode on all the channels (whether
active or not).
* prepare must find what channel the current frame is, and run on
behalf of that channel.
* process updates the most recent DeviceStatus and statistics for the
channel of the frame that has just arrived, but generates updated
values working through the active channels in round-robin fashion.
One minor detail in process is that we don't want to change the
DeviceStatus metadata of the current frame, so we now pass this to the
AgcChannel's process method, rather than letting it find the
DeviceStatus in the metadata.
