Merge branch 'stmmac-next'

Andy Shevchenko says:

====================
stmmac: pci: various cleanups and fixes

There are few cleanups and fixes regarding to stmmac PCI driver.
This has been tested on Intel Galileo board with recent net-next tree.

Since v2:
- drop patch 5/5 since it will be part of a big change across entire subsystem

Since v1:
- remove already applied patch
- append patch 1/5
- rework patch 3/5 to be functional compatible with original code
====================
