net: phylink: add support for PCS supported_interfaces bitmap
Add support for the PCS to specify which interfaces it supports, which
can be used by MAC drivers to build the main supported_interfaces
bitmap. Phylink also validates that the PCS returned by the MAC driver
supports the interface that the MAC was asked for.
An empty supported_interfaces bitmap from the PCS indicates that it
does not provide this information, and we handle that appropriately.
