phylib: mdio-ofgpio ---> mdio-gpio

Rename mdio-ofgpio driver to mdio-gpio and make it work with
non OpenFirmware gpio implementation.

Aditional changes to mdio-ofgpio:
- use gpio_request() and gpio_free()
- place irq[] array in struct mdio_gpio_info
- add module description, author and license
- if NO_IRQ is not defined define it to 0
- add note about compiling this driver as module
- rename mdc and mdio function (were ugly names)
- change MII to MDIO in bus name
- add __init __exit to module (un)loading functions
- probe fails if no phys added to the bus
- kzalloc bitbang with sizeof(*bitbang)

Laurent, please test this driver under OF.

Please respin this patch in 2 pieces; 1 patch to move the file and 1
patch to make the changes.  It is difficult to review as a single
patch.
