Documentation in .yaml format and updates to the MAINTAINERS Also 'make dt_binding_check' is passed. Introduced rx-internal-delay-ps & tx-internal-delay-ps for RGMII internal delay along with min/max values. This is to address the Vladimir proposal from the previous revision. Hence Reviewed-by tag is not added as it needs a review again.
