We register a device in eth_register, thus we have to unregister it in
eth_unregister. Also, if the device we unregister is the current device,
we have to set the current eth_device to NULL so that it isn't used anymore.

MAC addresses are sometimes stored at unusual places. This
patch makes it possible to give a MAC address to a ethernet
device id. This is independent of the device actually being
present.

When retrieving the MAC address from EEPROM, we must notify the networking core
at eth registration time. Otherwise we get the 'No MAC address set' warning on
the first network access, and the MAC address is set to a random value instead
of the real one.

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

We used to eth_open/eth_halt the network devices during NetLoopInit
which is called whenever the user enters a network command.
Change this behaviour so that the current network device gets opened
when making it the current one.
With this change it's always possible to send packages and we are able
to implement a new network stack in the next step.

Instead of writing the MAC address into the hardware on device open time
write it to the hardware when the user changes the parameter. This
way a user can change the MAC address in the hardware without actually
using the device. This helps Linux Network drivers which expect a valid
MAC address on startup.

Currently U-Boot uses globally defined eth_* functions. This is
horribly unflexible. This patch replaces the global functions
with pointers from structs. We could also use CONFIG_NET_MULTI,
but this has other implications, though we should merge this
some day.
Also, U-Boot has no unique way to handle MAC addresses. Each and
every board and network driver uses it's own mechanism to set the
MAC address. There are several problems which I've for too often.
For example everything goes well if we boot from network, but when
we boot from flash U-Boot forgets to set the MAC address and the
linux network driver has none.
This patch adds [gs]et_mac_address to the eth_device struct and
handles it as follows:
- First try to get a valid MAC address from the EEPROM and set
'ethaddr' accordingly.
- If no valid MAC address is found in the EEPROM (or no EEPROM is
connected), we set the devices MAC address from 'ethaddr'
This is done in eth_initialize which is called on startup for
every board.
This patch adds support for the Prodrive P3M750 (PPC750 & MV64460)
and the P3M7448 (MPC7448 & MV64460) PMC modules. Both modules are
quite similar and share the same board directory "prodrive/p3mx"
and the same config file "p3mx.h".

[This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still
sufferes from licensing issues. Blame Intel.]
