====================
convert stmmac glue layers into platform drivers

This patch set aims to convert the current dwmac glue layers into
proper platform drivers as request by Arnd[1]. These changes start
from patch 3 and onwards.

Overview:
Platform driver functions like probe and remove are exported from
the stmmac platform and then used in subsequent glue later
conversions. The conversion involes adding the platform driver
boiler plate code and adding it to the build system. The last patch
removes the driver from the stmmac platform code thus making it into
a library for common platform driver functions.

The two first patches adds glue layer for my platform. I chose to
first add old style glue layer and then convert it. The churn this
creates is just 3 lines.

I would be very nice if people could test this patch set on their
respective platform. My testing has been limited to compiling and
testing on my (LPC18xx) platform. Thanks!

Next I will look into cleaning up the stmmac platform code.
