This condenses the opal node searching into a single function that finds
all compatible nodes, instead of just searching the ibm,opal children,
for ipmi, flash, and prd similar to how opal-i2c nodes are found.

Hi Michael,
It seems this patch hasn't made it in. Without it linux cannot find the
flash on p9 as skiboot has moved the node to a more appropriate place.
Thanks,
Cyril
