Having the id field be an int was making more complex bus topologies
excessively difficult.  For now, just convert it to a string, and
change all instances of "bus->id = val" to
snprintf(id, MII_BUS_ID_LEN, "%x", val).

This gets the FEC ethernet driver working again on the lite5200
platform.

The FEC driver is also compatible with the MPC5200, not only with the
MPC5200B, so this adds a suitable entry to the driver's match list.
Furthermore this adds the settings for the PHY in the dts file for the
Lite5200.  Note, that this is not exactly the same as in the
Lite5200B, because the PHY is located at f0003000:01 for the 5200, and
at :00 for the 5200B.  This was tested on a Lite5200 and a Lite5200B,
both booted a kernel via tftp and mounted the root via nfs
successfully.

Update MPC5200 drivers to also look for compatible properties in the
form "fsl,mpc5200-*" to better conform to open firmware generic names
recommended practice as published here:

http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html

This patch should *not* break compatibility with older device trees
which do not use the 'fsl,' prefix.  The drivers will still bind against
the older names also.

If you need to find a difference between addresses of two
struct members, subtract offsetof() or cast addresses to
char * and subtract those if you prefer it that way.  Doing
that same with s/char */u32/, OTOH...

The mpc5200 fec driver is corrupting memory. This patch fixes two bugs
where the wrong skb was being referenced.

This helps to allow the Fedora installer to use the built-in Ethernet on
the Efika for a network install.

Driver shouldn't complain if the register range is larger than what
it expects.  This works around failures with some device trees.
