wifi: rt2800soc: allow loading from OF

Add a single binding to help the already present dts files load the
driver. More are possible but there doesn't seem to be a significant
difference between them to justify this.

Use wifi name per dtschema requirements.

Added OF dependency to SOC CONFIG as adding of_match_table without OF
being present makes no sense.
