ipa: raspberrypi: Pass lens shading table through configure() function

The IPAInterface::configure() function now accepts custom configuration
data. Use it to pass the lens shading table instead of using a custom
IPA event. This will allow starting the IPA when starting the camera,
instead of pre-starting it early in order to process the lens shading
table allocation event.
