hw/ppc: Remove unused ppcuic_init()

Browse source 
Now we've converted all the callsites to directly create the QOM UIC
device themselves, the ppcuic_init() function is unused and can be
removed. The enum defining PPCUIC symbolic constants can be moved
to the ppc-uic.h header where it more naturally belongs.
