net: phylink: require supported_interfaces to be filled

Browse source

We have been requiring the supported_interfaces bitmap to be filled in
by MAC drivers that have a mac_select_pcs() method. Now that all MAC
drivers fill in the supported_interfaces bitmap, it is time to enforce
this. We have already required supported_interfaces to be set in order
for optical SFPs to be configured in commit f81fa96d8a ("net: phylink:
use phy_interface_t bitmaps for optical modules").

Refuse phylink creation if supported_interfaces is empty, and remove
code to deal with cases where this mask is empty.
