pipeline: ipa: raspberrypi: Move ControlInfoMap to the IPA

Currently the pipeline handler advertises controls handled by the IPA from a
static ControlInfoMap defined in the raspberrypi.h header. This change removes
this header file, and instead the IPA returns the ControlInfoMap to the pipeline
handler from the ipa::init() function. This is done to allow the IPA to adjust
the limits of the controls based on the sensor mode in a subsequent change.
