When a new parameter buffer needs to be queued, we need to specify which
algorithm is activated or not in the ISP. Add a simple prepare function
in AGC for that, which may later evolve to take the exposure locking
into account. For that function to be called, we also need to add the
loop on the algorithms in IPARkISP1::queueRequest.

We no longer disable the AE algorithm based on the controls::AeEnable,
which will be handled in a different manner later.
