bsps/aarch64: Use MMU pages appropriately
There were two bugs with MMU page use that were partially hiding each
other. The linker script page table section was 4x the size it needed to
be and the page table allocation routine was allocating pages PTRSIZE
times larger than it needed to. On ILP32, this resulted in incorrect but
functional allocation. On LP64, this resulted in allocation failures
earlier than expected.
