Merge branch 'stmmac-cleanups-for-stmmac_mdio_reset'

Martin Blumenstingl says:

====================
stmmac: cleanups for stmmac_mdio_reset

This is a successor to my previous series "stmmac: honor the GPIO flags
for the PHY reset GPIO" from [0]. It contains only the "cleanup"
patches from that series plus some additional cleanups on top.

I broke out the actual GPIO flag handling into a separate patch which
is already part of net-next: "net: stmmac: use GPIO descriptors in
stmmac_mdio_reset" from [1]

I have build and runtime tested this on my ARM Meson8b Odroid-C1.
