Use a single constant to define the sizes of the physmap[], phys_avail[],

and dump_avail[] arrays so they are in sync (previously it was possible
to store more entries in the physmap[] then we could store in phys_avail[],
which was pointless).  While I'm here, bump up the length of these tables
to hold 30 entries on amd64 and 16 on i386.  This allows machines with
fairly fragmented memory maps to boot ok (at least one machine would
not boot FreeBSD/i386 but would boot FreeBSD/amd64 because amd64 allowed
for more fragments).
