Log Message:
- Move all of the stuff-missing-from-OFW-device-tree stuff into a
new function sparc64_device_tree_fixup(), and call it from
device_register().
- sparc64_device_tree_fixup() is table-driven, selecting the table
based on the machine_model. It can appy "dtnode" fixups (by matching
the device's OFW path) and "special" fixups, which are especially
useful when a property needs to be added to another device that happens
to not be in the OFW device tree.
- Implement enumeration of missing-from-OFW-device-tree i2c devices
by "sub-classing" the controller's device handle, intercepting the
"i2c-enumerate-devices" device call. We let the "super" first
enumerate any i2c devices that are in the OFW device tree, and then
enumerate our own additions after that is done. i2c additions are
provided by the machine_model fixup tables.
