include/net/if.h: Add mechanism for MMD access with SIOCxMIIREG ioctls

Browse source 
Add mdio_phy_id_c45 macro. This macro allows encoding of additional information
needed for MMD access into the phy_id field of the mii_ioctl_data_s structure.
This macro is intended for use by user applications.

Add macros for decoding the phy_id encoded with the mdio_phy_id_c45 macro.
These macros are intended for use by network drivers implementing
SIOCxMIIREG commands.
