phylib: add *_direct() variants of phy_connect and phy_attach functions

Browse source 
Add phy_connect_direct() and phy_attach_direct() functions so that
drivers can use a pointer to the phy_device instead of trying to determine
the phy's bus_id string.

This patch is useful for OF device tree descriptions of phy devices where
the driver doesn't need or know what the bus_id value in order to get a
phy_device pointer.
