====================
stmmac: dwmac-sti refactor+cleanup

This patch set aims to remove the init/exit callbacks from the
dwmac-sti driver and instead use standard PM callbacks. Doing this
will also allow us to cleanup the driver.

Eventually the init/exit callbacks will be deprecated and removed
from all drivers dwmac-* except for dwmac-generic. Drivers will be
refactored to use standard PM and remove callbacks.
