If we call phylink_caps_to_linkmodes directly from phylink_get_linkmodes, it is difficult to re-use this functionality in MAC drivers. This is because MAC drivers must then work with an ethtool linkmode bitmap, instead of with mac capabilities. Instead, let the caller of phylink_get_linkmodes do the conversion. To reflect this change, rename the function to phylink_get_capabilities.
