media: v4l2-fwnode: add v4l2_fwnode_connector
Currently every driver needs to parse the connector endpoints by it self.
This is the initial work to make this generic. A generic connector has
common members and connector specific members. The common members are:
- type
- label (optional)
- links
- nr_of_links
The specific members are stored within a union, since only one of them
can be available at the time. Since this is the initial support the
patch adds only the analog-connector specific ones.

v10:
- drop unused V4L2_CONN_HDMI support
v8:
- rename CON -> CONN
- supported_tvnorms_stds -> sdtv_stds and adapt description
v7:
- fix spelling issues
- constify label
- support variable label size
- replace single remote_port/id members by links member of variable
size
- squash v4l2-connector into v4l2-fwnode
@Jacopo: I dropped your r b tag because I changed the port/id logic.
v6:
- fix some spelling and style issues
- rm unnecessary comments
- drop vga and dvi connector
- fix misspelt connector
v2-v4:
- nothing since the patch was squashed from series [1] into this
series.
