Moving Emaclite to DM + MDIO support

Hi,

The first part of this series is about adding MDIO support to driver which was out of mainline and it was much easier to merge it before move to DM. Then driver didn't use indirect register access. In the middle of moving this driver I have fixed logic in some functions which doesn't affect performance of this driver.
All these changes were tested on HW design with emaclite with and without pong buffers.

This patch series depends on microblaze cleanup series. All these patches will be available in
git://git.denx.de/u-boot-microblaze.git
also with patches which I am going to send now.

Thanks,
Michal
