ipa: raspberrypi: Add sensor mode limits to CameraMode

Add fields in the CameraMode structure to capture the mode specific
limits for analogue gain and shutter speed. For convenience, also add
fields for minimum and maximum frame durations.

Populate these new fields when setting up the CameraMode structure.
