[PATCH] dt-bindings: display: bridge: ldb: Add check for reg and reg-names

[Marek Vasut <marek.vasut@mailbox.org>]

Make "reg" property mandatory for all LDB devices and "reg-names"
mandatory for i.MX8MP and i.MX93 which have two "reg" values. The
i.MX6SX has only one "reg" value so the "reg-names" property there
is optional and not needed.
