dts: edtlib: Sanity-check the final merged binding only
Sanity-checking each !included file separately was inherited from the
old scripts. It makes it messy to check that combinations of fields make
sense, e.g. to check 'const:' or 'default:' against 'type:', since those
fields might come from different files (this is handy, since it makes
sense to just add/change a 'const:' value, for example).
Drop the requirement that each !included file is a complete binding in
itself, and treat them as binding fragments instead. Only check the
final merged binding.
This also means that !included files no longer need to have a
'description:' or 'title:' (those have always been unused for !included
files), so remove those, and add comments that explain what the
fragments are for instead. That should demystify bindings a bit.
Also fix the descriptions of i2c.yaml, i2s.yaml, spi.yaml, and
uart.yaml. They're for controllers, not devices. These are copy-paste
error from the corresponding device .yaml files.
Piggyback some indentation consistency nits in binding-template.yaml.
