x86/efi: Correct EFI boot stub use of code32_start
commit 7e8213c1f3acc064aef37813a39f13cbfe7c3ce7 upstream.
code32_start should point at the start of the protected mode code, and
*not* at the beginning of the bzImage. This is much easier to do in
assembly so document that callers of make_boot_params() need to fill out
code32_start.
The fallout from this bug is that we would end up relocating the image
but copying the image at some offset, resulting in what appeared to be
memory corruption.
