kernel - Fix boot issues with > 512GB of ram

* Fix DMAP installation issues for kernels with > 512GB of ram.
  The page table was not being laid out properly for PML4e
  entries past the first one.

* Fix early panic reporting.  Conditionalize the lapic access as the
  lapic might not exist yet.

* Tested to 1TB of ram.  Theoretically DragonFlyBSD can support up
  to 32TB of ram (and slightly less than ~64TB with one #define
  change).
