net: mdio-gpio: Add support for separate MDI and MDO gpio pins
This is for a system with fixed assignments of input and output pins
(various variants of Kontron COMe).

net: mdio-gpio: Add support for active low gpio pins
Some systems using mdio-gpio may use active-low gpio pins
(eg with inverters or FETs connected to all or some of the
gpio pins).

mdio-gpio: Add reset functionality to mdio-gpio driver(v2).
This patch adds phy reset functionality to mdio-gpio driver. Now
mdio_gpio_platform_data has new member as function pointer which can be
filled at the bsp level for a callback from phy infrastructure. Also the
mdio-bitbang driver fills-in the reset function of mii_bus structure.
Without this patch the bsp level code has to takecare of the reseting
PHY's on the bus, which become bit hacky for every bsp and
phy-infrastructure is ignored aswell.

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.
