[coreboot] [PATCH] Multiboot bugfix (coreboot-v3)

I noticed a problem in the multiboot memory map in v3. Instead of the
the reason being that the multiboot map is generated too early in
arch_write_tables(), before a number of routines that write/reserve
stuff are executed (in my test this only affects the 0x0-0x500 region
but I notice there's other stuff too).
Attached patch moves it down, solving the problem. Because stage1 can no
longer assume the MBI is at 0xf0000, I had to add a return path for stage2
to give it a pointer, using its exit status value.
As collateral benefit, my patch removes the FIXME about PIRQ alignment.
The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and
how) you may access your data; but nobody's threatening your freedom: we
still allow you to remove your data and not access it at all."
