[PATCH v2] dt-bindings: serial: rs485: remove deprecated .txt binding stub

[PATCH v2] dt-bindings: serial: rs485: remove deprecated .txt binding stub

[Akash Sukhavasi]

The plain text binding file was superseded by the YAML schema in
commit d50f974c4f7f ("dt-bindings: serial: Convert rs485 bindings
to json-schema"). The file now contains only a redirect notice.
Remove it, and update references in serial_core.c and
serial-rs485.rst to point to the YAML schema.

- Update references in serial_core.c and serial-rs485.rst to point
  to rs485.yaml (Sashiko review).

Unless I am missing something about how docs.kernel.org redirects
magically work or something along those lines,
Acked-by: Conor Dooley <conor.dooley@microchip.com>
pw-bot: not-applicable
