From: Kieran Bingham via libcamera-devel <libcamera-devel@lists.libcamera.org>

Pass the current frame number, and the current FrameContext for calls to
prepare.

Until there is a Frame Context Queue in the RKISP1 the FrameContext will
be a nullptr, and must not be dereferenced until the queue is
implemented.

Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

 - Obtain and use the RKISP1FrameContext Queue entry for IPARkISP1::fillParamsBuffer

Hi Jacopo

Thank you for the patch.

I think there is FCQueue in RkISP1 now, so should this commit message be 
updated accordingly?

Won't this copy IPU3FrameContext ? I think here we need

     IPU3FrameContext &frameContext = context_.frameContexts.get(frame);
