msm: camera: icp: Fix AHB, AXI voting in icp

Due to a mismatched internal structure num_paths for
AXI voting is always set to 0 for ipe, bps which is
causing not to vote any AXI bandwidth for these hws.
After all contexts associated with a device go to
inactive state, reduce the AHB vote to minimum value
to make sure previously voted high AHB vote doesn't
remain for the rest of camera session.
