The is does a general cleanup of the drivers/net/ Kconfig and
Makefile.  This patch create a "core" option and places all
the networking core drivers into this option (default is yes
for this option).  In addition, it alphabitizes the Kconfig
driver options.

As a side cleanup, found that the arcnet, token ring, and PHY
Kconfig options were a tri-state option and should have been
a bool option.

This patch adds the IC+ IP1001 (Gigabit Ethernet Transceiver) driver.
I've had to add an additional delay (2ns) to adjust RX clock phase at
GMII/ RGMII interface (according to the PHY data-sheet). This helps to
have the RGMII working on some ST platforms.

The kernel doesn't have a symbol called BCM63XX.  There is a symbol
BCM63XX_ENET (introduced in 9b1fc55a, 6 weeks after 09bb9aa0 that
introduced BCM63XX_PHY), but the driver compiles without that, too.

The Octeon SOC has two types of Ethernet ports, each type with its own
driver.  However, the PHYs for all the ports are controlled by a
common MDIO bus.  Because the mdio driver is not associated with a
particular driver, but is instead a system level resource, we create s
stand-alone driver for it.

As for the driver, we put the register definitions in
arch/mips/include/asm/octeon where most of the other Octeon register
definitions live.  This is a platform driver with the platform device
for "mdio-octeon" being registered in the platform startup code.

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.

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.
