Merge branch 'stmmac-next' 

Giuseppe Cavallaro says:

====================
stmmac: review driver Koptions

Recently many Koption options have been added to have new glue logic on several
platforms.

The main goal behind this work is to guarantee that the driver built
fine on all the branches where it is present independently of which
glue logic is selected.

IMHO, it is better to remove all the not necessary Koption(s) that can hide
build problems when something changes in the driver and especially when
the DT compatibility allows us to manage all the platform data.

I compiled the driver w/o any issue on net-next Git for:

  x86, arm and sh4.

In case of there are build problems on some repos now it will be
easy to catch them and cherry-pick patches from mainstream.

For sure, do not hesitate to contact me in case of issue.

Also this set removes STMMAC_DEBUG_FS and BUS_MODE_DA. The latter is useless
and the former can be replaced by DEBUG_FS (always to make safe the build).

V2: patch-set re-based on top of the latest updates for net-next
