x86: reserve_early end-of-conventional-memory to 1MB, 64-bit

Browse source

Explicitly reserve_early the whole address range from the end of
conventional memory as reported by the bios data area up to the
1Mb mark. Regard the info retrieved from the BIOS data area with
a bit of paranoia, though, because some biosses forget to register
the EBDA correctly.
