x86: handle initrd that extends into unusable memory
commit 8c5dd8f43367f4f266dd616f11658005bc2d20ef upstream.
On a system where system memory (according e820) is not covered by
mtrr, mtrr_trim_memory converts a portion of memory to reserved, but
bootloader has already put the initrd in that range.
Thus, we need to have 64bit to use relocate_initrd too.
[ Impact: fix using initrd when mtrr_trim_memory happen ]
