_lmb_alloc_addr() returns -EINVAL when a reservation overlaps an

when it does not overlap any bank at all.
So for the partial-overlap case, it returns -EINVAL and
boot_fdt_handle_region() in boot/image-fdt.c prints "ERROR: reserving
fdt memory region failed" during boot which makes it sound like a
serious error.
The commit message does not explain why do you think the overlap is not
a serious error, and why it could be ignored.
