Add a uclass which provides access to MDIO busses and includes operations required by MDIO. The implementation is based on the existing mii/phy/mdio data structures and APIs. This patch also adds device tree binding for MDIO bus.

Changes in v4:
- Minor updates for comments and Maintainer.
Changes in v3:
- Move mdio uclass implementation to driver/net folder;
- Replace flat-tree functions with livetree functions and update codes and comments to be consistent with driver-model codes style;
- Put struct mii_dev to uclass platdata to avoid the mdio alloc and let driver model framework to alloc the memroy automatically, meanwhile the mii bus link initialization is added.
Changes in v2:
Fix error printing:
Change some debug to pr_err;
mii bus has no parent member and it is not a udevice, so dev_err is changed to pr_err for mii bus error printings.
