ipa: raspberrypi Store the target string in the controller

The target string may be used by algorithms to determine the running
hardware target.

Store the target string provided by the camera tuning files in the
controller state. Add a getTarget() member function to retrieve this
string.

Validate the correct hardware target ("bcm2835") during the IPA
initialisation phase.
