net: phy: introduce phy_id_compare_vendor() PHY ID helper

Browse Source 
Introduce phy_id_compare_vendor() PHY ID helper to compare a PHY ID with
the PHY ID Vendor using the generic PHY ID Vendor mask.

While at it also rework the PHY_ID_MATCH macro and move the mask to
dedicated define so that PHY driver can make use of the mask if needed.
