Subject: [PATCH net-next v3 01/11] net: phy: get rid of redundant is_c45
 information

phy_device_create() will be called with is_c45 and c45_ids. If c45_ids
are set, is_c45 is (usually) true. Change the only caller which do
things differently, then drop the is_c45 check in phy_device_create().

This is a preparation patch to replace the is_c45 boolean with an enum
which will indicate how the PHY is accessed (by c22, c45 or
c45-over-c22).
