net: stmmac: rk: introduce flags indicating support for RGMII/RMII

Browse source

Introduce two boolean flags into struct rk_priv_data indicating
whether RGMII and/or RMII is supported for this instance. Use these
to configure the supported_interfaces mask for phylink, validate the
interface mode. Initialise these from equivalent flags in the
rk_gmac_ops or depending on the presence of the ops->set_to_rgmii and
ops->set_to_mii methods. Finally, make ops->set_to_* optional.

This will allow us to get rid of empty set_to_rmii() methods.
