====================
Add Hisilicon MDIO bus driver and FEMAC driver

This patch set adds a Hisilicon MDIO bus driver and
a Fast Ethernet MAC(FEMAC) driver.
We also abstract a general interface "of_phy_get_and_connect"
for PHY connect. User will have no bother with getting
"phy-mode" and "phy-handle" any more.

Changes in v1:
- Pass private data structure instead of struct mii_bus
  in MDIO read and write operation.
- Return the error which devm_clk_get() gives when MDIO probe.
- Leave the clock unprepared and disabled on error when MDIO probe.
- Abstract a general interface "of_phy_get_and_connect" for PHY connect.
- Remove the "_reset" suffixes in "reset-names" property.
- Enable tx per-packet interrupt when tx fifo full.
- Remove pointless compatible and add SoC specific compatible.
- Declare only one clock in MAC dts documentation.
- Add standard unit suffixes for "phy-reset-delays".
- Use a smaller NAPI poll weight 16 for our Fast Ethernet MAC.
- Use phy_ethtool_{get|set}_link_ksettings for ethtool ops.
- Use phydev from struct net_device in MAC driver.
