ipa: rpi: agc: Reorganise code for multi-channel AGC
This commit does the basic reorganisation of the code in order to
implement multi-channel AGC. The main changes are:
* The previous Agc class (in agc.cpp) has become the AgcChannel class
in (agc_channel.cpp).
* A new Agc class is introduced which is a wrapper round a number of
AgcChannels.
* The basic plumbing from ipa_base.cpp to Agc is updated to include a
channel number. All the existing controls are hardwired to talk
directly to channel 0.
There are a couple of limitations which we expect to apply to
multi-channel AGC. We're not allowing different frame durations to be
applied to the channels, nor are we allowing separate metering
modes. To be fair, supporting these things is not impossible, but
there are reasons why it may be tricky so they remain "TBD" for now.
This patch only includes the basic reorganisation and plumbing. It
does not yet update the important methods (switchMode, prepare and
process) to implement multi-channel AGC properly. This will appear in
a subsequent commit. For now, these functions are hard-coded just to
use channel 0, thereby preserving the existing behaviour.
