Log Message:
implement dumpsys() and friends for arm64.

this is almost a direct copy of the arm code, which is simply
as the basic structures about physical memory are the same
between arm and arm64.  the main change i made was to use
the direct map instead of a virtual dump page that is remapped
to whatever physical page is being dumped.

i also changed the existing cpu_kcore_hdr_t to include the
missing number of ram segments.

note that this is not a complete solution for crash dumps yet,
as the libkvm code needs some work.  i'm fairly positive that
this side is correct, as i can see the data i expect to see,
but libkvm's _kvm_kvtop() function returns garbage so far.

there is no "minidump" support here yet, ala amd64, but we
probably want it eventually.

ok skrll@.
