Add patch fixing rmmod and insmod. Lots of flawed logic fixed that
permits the module to correctly rmmod and insmod later.
Just to quote some change, use phy_detach instead of phy_disconnect, fix
exclusive reset_control that could only be used once, fix kernel panic
on second edma_cleanup, stop traffic before module exit...
