tegra132: split memory range querying to above/below 4GiB
The address map code was originally assuming all carveouts would
be packed together in the upper end of the physical memory
address space. However, the trust zone carveout is always in the
32-bit address space. Therefore, one needs to query memory ranges
by above and below 4GiB with the assumption of carveouts being
packed at the top of *each* resulting range.
