4b16f8e2d6 powerpc: various straight conversions from module.h --> export.h
All these files were including module.h just for the basic
EXPORT_SYMBOL infrastructure.  We can shift them off to the
export.h header which is a way smaller footprint and thus
realize some compile time gains.

4b6ba8aacb of/net: Move of_get_mac_address() to a common source file.
There are two identical implementations of of_get_mac_address(), one
each in arch/powerpc/kernel/prom_parse.c and
arch/microblaze/kernel/prom_parse.c.  Move this function to a new
common file of_net.{c,h} and adjust all the callers to include the new
header.

e58ca3de64 [POWERPC] Fix problems with device tree representation of TSI-1xx bridges
This fixes some problems with the way the some things
represented in the device tree for the Holly and Taiga boards.  This
means changes both to the dts files, and to the code which
instantiates the tsi108 ethernet platform devices based on the device
tree.

	- First, and most importantly, the ethernet PHYs are given
with an identical 'reg' property.  This reg currently encodes the
accessible register used to initiate mdio interaction with the PHYs,
rather than a meaningful address on the parent bus (mdio in this
case), which is incorrect.  Instead we give the address of these
registers as 'reg' in the mdio node itself, and encode the ID of each
phy in their 'reg' propertyies.
	- Currently the platform device constructor enables a
workaround in the tsi108 ethernet driver based on the compatible
property of the PHY.  This is incorrect, because the workaround in
question is necessary due to the board's wiring of the PHY, not the
model of PHY itself.  This patch alters the constructor to instead
enable the workaround based on a new special property in the PHY node.
	- The compatible properties on a number of nodes in the device
tree are insufficiently precise.  In particular the PHYs give only
"bcm54xx", which is broken, since there are many bcm54xx PHY models,
and they have differences which matter.  The mdio had a compatible
property of "tsi-ethernet" identical to the ethernet MAC nodes, which
doesn't make sense.  The ethernet, i2c, bridge and PCI nodes were
given only as "tsi-*" which is somewhat inprecise, we replace with
"tsi108-*" in the case of Taiga (which has a TSI108 bridge), and
"tsi109-*", "tsi108-*" in the case of Holly (which has a TSI109
bridge).
	- We remove some "model" properties from the ethernets on
Taiga board which were neither useful nor adequately precise.
	- On Holly we change to using a dtc label instead of a full
path to reference the MPIC node, which makes the dts a little more
readable.

c1b78d05b3 [POWERPC] Generalize tsi108 PHY types
Add a phy_type field to the tsi108 ethernet structures to indicate which PHY
is used on a board.  This is derived from the "compatible" property in the
ethernet-phy node of the device tree.  The default remains the MV88E PHY.

Also, convert the setup code to use of_get_mac_address instead of hard coding
a lookup for the "address" property in the ethernet node.
