mb/emulation/qemu-i440fx: Reserve low memory
Ensure that the low memory is properly reserved so it does not get
marked as normal RAM and get wiped or reused by firmware or the kernel.
This ensures that the low RSDP is always available for the kernel.
This is only noticed if something wipes the RSDP before the kernel
boots, which happens if you use the depthcharge payload and boot in
developer mode.
