x86: drop use of E801 memory "map" (and alike)

ACPI mandates use of E820 (or newer, e.g. EFI), and in fact firmware
has been observed to include E820_ACPI ranges in what E801 reports as
available (really "configured") memory. Since all 64-bit systems ought
to support ACPI, drop our use of older BIOS and boot loader interfaces.
