There apparently is no reason to require 3 queued buffers to call streamon() for the RkISP1 as the driver operates with a scratch buffer where frames can be directed to if there's no available buffer provided by userspace. Reduce the number of required buffers to 1 to allow applications to operate with a single queued buffer. Tested with libcamera, by operating with a single capture request. The same request (and associated capture buffer) gets recycled once completed. This of course causes a frame rate drop but doesn't hinder operations.
