vpnor: create hostboot bootloader partition
The hostboot bootloader code doesn't use mbox.
It has specific requirements:
- The PNOR TOC should be at the 'PNOR end - TOC size - page size'
offset. It searches for the TOC here, if not found, the search moves
down page by page.
- The PNOR should be 64M. The page size and erase block should be 4K.
The TOC should be 32K.
Copy what the bootloader expects to the LPC memory when mboxd starts up.
The same needs to be done in the case of an mbox reset (irrespective of
where the reset comes from).
Skiboot expects that the TOC should be at offset 0, but it uses mbox to
read the TOC. So this commit doesn't impact skiboot requirements.
