Subject: [RFC PATCH 06/12] media: iris: Update CAPTURE format info based on OUTPUT format

Update the width, height and buffer size of CAPTURE based on the
resolution set to OUTPUT via VIDIOC_S_FMT. This is required to set the
updated capture resolution to firmware when S_FMT is called only for
OUTPUT.
