pinctrl: dt-bindings: Fix some errors in the lgm and pinmux schema

This fixes some problems that caused build errors in the
lgm-io schema file:

- No "bindings" infix in the schema id
- Move the allOf inclusion for pinconf and pinmux nodes into
  the patternProperties for the -pins node
- We want "groups" not "group" to be compulsory for a pinmux
  node blended with a pin config node.
- Fix the generic pinmux-schema to list "groups" rather than
  "group" for a pinmux node, this might have led to some confusion.

This is a first user of the generic schema so a bit of a bumpy
road.

This was applied directly to fix compile errors in -next
so please advice quickly if I added further bugs...

Thanks a lot Linus. Sorry for the inconvenience.

Hi Rob,

Sorry about the mistake. FWIW, i did run make dt_binding_check and ensured
that CHKDT step passes. But its obvious that i missed something. Let me
figureout what i missed to avoid making same mistakes in future.

Regards,
Rahul
