[PATCH] swap real_to_prot() and prot_to_real() (Re: [PATCH] i386-qemu port)

[Robert Millan]

When doing the i386-coreboot port I made this choice completely backwards.

I thought real_to_prot() was only useful on i386-pc, because we needed it
for returning from BIOS, and prot_to_real() was useful elsewhere, because
the Linux loader would use it.

Turns out we need real_to_prot() on i386-qemu for the initial transition
to i386 mode, AND we don't need prot_to_real() anywhere other than i386-pc,
because OSes that expect to be loaded in i8086 mode are going to rely on
BIOS calls.

So this patch swaps them.  real_to_prot() goes to realmode.S and
prot_to_real() back to startup.S.
