Some phys have additional registers that are not covered by standard. Access to this registers can be done via specific sequence according to the phy datasheet. The driver for Micrel phy contains some additional function, that the board maintainer can call to tune the phy. However, these registers cannot be accessed with "mmdio" command.
Add calback to the phy API to allow to call the function for reading / writing extended registers with the mmdio command.
