of/address: check for invalid range.cpu_addr

[ Upstream commit f49c7faf776f16607c948d852a03b04a88c3b583 ]

Currently invalid CPU addresses are not being sanity checked resulting in
SATA setup failure on a SynQuacer SC2A11 development machine. The original
check was removed by and earlier commit, so add a sanity check back in
to avoid this regression.
