pipeline: rkisp1: Move ControlInfoMap to IPA module

Currently the pipeline handler advertises controls handled by the IPA
from a ControlInfoMap it manually constructs. This is wrong, as the IPA
module is the component that knows what controls it supports. Fix this
by moving the ControlInfoMap construction to the IPA module, and pass it
to the pipeline handler as a return value from the IPA init() function.
