====================
r8169: add phylib support

Now that all the basic refactoring has been done we can add phylib
support. This patch series was successfully tested on:
RTL8168h
RTL8168evl
RTL8169sb

Changes in v2:
- return error in mdio ops if phyaddr > 0
- advertise pause modes
- added reviewed-by for several patches

Changes in v3:
- return ENODEV for unused phy addresses in mdio ops
- remove unneeded PHY suspend in patch 2
- use recently added phy_speed_down and phy_speed_up in patch 7
- other minor changes based on review comments
