The MEDIA_PAD_FL_MUST_CONNECT flag indicates that the pad requires an
enabled link to stream, but only if it has any link at all. This makes
little sense, as if a pad is part of a pipeline, there are very few use
cases for an active link to be mandatory only if links exist at all. A
review of in-tree drivers confirms they all need an enabled link for
pads marked with the MEDIA_PAD_FL_MUST_CONNECT flag.

Expand the scope of the flag by rejecting pads that have no links at
all. This requires modifying the pipeline build code to add those pads
to the pipeline.

The struct v4l2_subdev_client_capability was never actually documented,
only the capability flags were documented.

Add this.

Drop duplicated UAPI specific portions of the CCS (kernel) documentation
and fix a spelling error in UAPI documentation previously fixed in driver
documentation.

Also add references both ways.

Pull media updates from Mauro Carvalho Chehab:

 - v4l core: subdev frame interval now supports which field

 - v4l kapi: moves and renames the init_cfg pad op to init_state as an
   internal op.

 - new sensor drivers: gc0308, gc2145, Avnet Alvium, ov64a40, tw9900

 - new camera driver: STM32 DCMIPP

 - s5p-mfc has gained MFC v12 support

 - new ISP driver added to staging: Starfive

 - new stateful encoder/decoded: Wave5 codec It is found on the J721S2
   SoC, JH7100 SoC, ssd202d SoC. Etc.

 - fwnode gained support for MIPI "DisCo for Imaging"
   (https://www.mipi.org/specifications/mipi-disco-imaging)

 - as usual, lots of cleanups, fixups and driver improvements.
