powerpc/85xx: verify the localbus device tree address before booting the OS
The localbus controller node in the device tree is typically a root node,
even though the controller is part of CCSR. If we were to put the lbc
node under the SOC node, then the 'ranges' property in the lbc node would
translate through the 'ranges' property of the parent SOC node, and we
don't want that.
Since the lbc is a separate node, it's possible for the 'reg' property to
be wrong. This happened with the original version of p1022ds.dts, which
used a 32-bit value in the 'reg' address, instead of a 36-bit address.
