media: nxp: imx8-isi: Mark all crossbar sink pads as MUST_CONNECT 

[ Upstream commit 9b71021b2e ]

All the sink pads of the crossbar switch require an active link if
they're part of the pipeline. Mark them with the
MEDIA_PAD_FL_MUST_CONNECT flag to fail pipeline validation if they're
not connected. This allows removing a manual check when translating
streams.
