[PATCH] x86/boot: Fix PVH boot following the start of the MBI->BI conversion

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

pvh_init() sets up the mbi pointer, but leaves mbi_p at 0.  This isn't
compatbile with multiboot_fill_boot_info() starting from the physical address,
in order to remove the use of the mbi pointer.

Fixes: 038826b61e85 ("x86/boot: move x86 boot module counting into a new 
boot_info struct")

This is a testiment to how tangled the boot code really is.
