[PATCH 2/2] media: staging: rkisp1: add the flag MEDIA_PAD_FL_METADATA to the metadata pads

[Dafna Hirschfeld <dafna.hirschfeld@collabora.com>]

The 4 pads of the links between kisp1_isp and the params
and stats entities transmit metadata. This patch
adds the flag MEDIA_PAD_FL_METADATA to those pads.
In addition it initializes the width and height of
the pads formats to 0 since metadata format has no
dimensions.

This fixes the TODO item:
"Fix pad format size for statistics and parameters entities."
So the patch also removes this item.
