net: phy: re-design phy_modes to be self-contained
of_get_phy_mode() uses a local array to map phy_interface_t values from
include/linux/net/phy.h to a string which is read from the 'phy-mode' or
'phy-connection-type' property. In preparation for exposing the PHY
interface mode through sysfs, perform the following:
- mode phy_modes from drivers/of/of_net.c to include/linux/phy.h such
that it is right below the phy_interface_t enum
- make it a static inline function returning the string such that we can
use it by just including include/linux/net/phy.h
- add a PHY_INTERFACE_MODE_MAX enum value to guard the iteration in
of_get_phy_mode()
