ipa: rpi: Apply default ControlInfo values for sensor controls

The existing IPA initialisation code did not set default values for
some sensor related controls. This caused a crash using libcamerify
when the it was trying to access the default value for
controls::FrameDurationLimits as part of a recent change.

Ensure controls::FrameDurationLimits, controls::AnalogueGain and
controls::ExposureTime advertise default values along with the existing
min/max values. The default is set to the defaults defined in the IPA
set during initialisation.
