of/sparc: convert various prom_* functions to use phandle
Rather than passing around ints everywhere, use the phandle type where appropriate for the various functions that talk to the PROM. Signed-off-by: Andres Salomon <dilinger@queued.net> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
