net: phylink: add phylink_expects_phy() method

Browse Source 
Provide phylink_expects_phy() to allow MAC drivers to check if it
is expecting a PHY to attach to. Since fixed-linked setups do not
need to attach to a PHY.

Provides a boolean value as to if the MAC should expect a PHY.
Returns true if a PHY is expected.
