f004f3ea34 phylib: make mdio-gpio work without OF (v4)
make mdio-gpio work with non OpenFirmware gpio implementation.

Aditional changes to mdio-gpio:
- use gpio_request() and gpio_free()
- place irq[] array in struct mdio_gpio_info
- add module description, author and license
- 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)

Changes since v3:
- keep bus naming "%x" to be compatible with existing drivers.

Changes since v2:
- more #ifdefs reduction
- platform driver will be registered on OF platforms also
- unified platform and OF bus_id to phy%i

Changes since v1:
- removed NO_IRQ
- reduced #idefs

Laurent, please test this driver under OF.

a79d8e93d3 phy/fixed.c: rework to not duplicate PHY layer functionality
With that patch fixed.c now fully emulates MDIO bus, thus no need
to duplicate PHY layer functionality. That, in turn, drastically
simplifies the code, and drops down line count.

As an additional bonus, now there is no need to register MDIO bus
for each PHY, all emulated PHYs placed on the platform fixed MDIO bus.
There is also no more need to pre-allocate PHYs via .config option,
this is all now handled dynamically.

function has been written, so that to free resources in correct way; the
release path is now clean.

Before the rework, it used to cause
 Device 'fixed@100:1' does not have a release() function, it is broken
 and must be fixed.

Also changed the notation of the fixed phy definition on

gianfar and ucc_geth that define phy_id strictly as "%d:%d" and cleaned up
the whitespace issues.
