[PATCH v2] Documentation: devicetree: meson-ir: "linux, rc-map-name" is supported

[martin.blumenstingl@googlemail.com (Martin Blumenstingl)]

The driver already parses the "linux,rc-map-name" property. Add this
information to the documentation so .dts maintainers don't have to look
it up in the source-code.
