sparc: unify openprom.h
After the preparational steps the unification was simple.
The linux_prom_pci_registers definition did not look like
it could be unified at first look since the structure is assigned
using prop_getproperty() / of_get_property() so the structure
is assumed to come direct form the prom.
The LINUX_OPPROM_MAGIC was kept even if it is not used by the kernel
on the assumption that userspace may require it.
