pipeline: ipa: raspberrypi: Add HBLANK control to DelayedControls
Update CamHelper::getDelays() to return the sensor HBLANK delay. The
HBLANK delay is set to the same value as VBLANK delay for all sensors in
the Raspberry Pi IPA.
Return the HBLANK gain delay from the IPA to the pipeline handler, and
initialise DelayedControls to handle V4L2_CID_HBLANK with this delay
value.
As a drive-by, check that the V4L2_CID_HBLANK control is available when
calling IPARPi::configure().
