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.
