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. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
