Log:
powerpc/mpc85xx: Fix localbus child reg property decoding
r302340, as an attempt to fix the localbus child handling post-rman change,
actually broke child resource allocation, due to typos in
fdt_lbc_reg_decode(). This went unnoticed because there aren't any drivers
currently in tree that use localbus.
