ipa: ipu3: convert AGC to the new algorithm interface

In preparation for using the AGC through the new algorithm interfaces,
convert the existing code to use the new function types.

Now that the process call is rewritten, re-enable the compiler flag to
warn when a function declaration hides virtual functions from a base class
(-Woverloaded-virtual).

We never use converged_ so remove its declaration. The controls may not
need to be updated at each call, but it should be decided on the context
side and not by a specific call by using a lock status in the Agc
structure for instance.

As the params_ local variable is not useful anymore, remove it here
too.
