Merge branch 'stmmac-dwmac-rk-PM' 



Joachim Eastwood says:

====================
stmmac: dwmac-rk: convert to standard PM/remove functions

This patch set aims to remove the init/exit callbacks from the
dwmac-rk driver and instead use standard PM callbacks. 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.

This conversion was pretty straight forward, but it would really nice
if some chromium people could test suspend/resume with this patch set.
