====================
net: phy: stop exporting phy_driver_register

Once the last user of a clock in dp83640 has been removed, the clock should
be removed. So far orphaned clocks are cleaned up in dp83640_free_clocks()
only. Add the logic to remove orphaned clocks in dp83640_remove().
This allows to simplify the code, and use standard macro
module_phy_driver(). dp83640 was the last external user of
phy_driver_register(), so we can stop exporting this function afterwards.
