rG32bb6a6925c0: arm64: Call pmap_bootstrap_dmap from initarm

Make pmap_bootstrap_dmap self contained and call it from initarm. This
will allow us to have a better view of excluded physical address space
when calling pmap_bootstrap.

Is there supposed to be a functional change here?

There should be no functional change in this patch. It is to allow D42734 to have a correct view of usable physical address space for its early allocations.
