The reason for this issues is that
Currently add_mem() tries to merge the memory banks if they are
continuous. Add a option to avoid this merge which is not always useful
e.g. for devices with memory > 4G.

The TTB area allocated for early MMU is now 64K instead of 16K, yet only
the old 16K were requested to ensure e.g. memtest doesn't touch them.
Fix this by requesting the full region.
