powerpc/ps3: Add gelic udbg driver 



Add a new udbg driver for the PS3 gelic Ehthernet device.

This driver shares only a few stucture and constant definitions with the
gelic Ethernet device driver, so is implemented as a stand-alone driver
with no dependencies on the gelic Ethernet device driver.
