[PATCH for-4.10 1/5] tools/dombuilder: Drop more PVH v1 leftovers

[Andrew Cooper <andrew.cooper3@citrix.com>]

alloc_magic_pages() is renamed to alloc_magic_pages_pv() to mirror its
alloc_magic_pages_hvm() counterpart.  Delete a redundant comment, introduce
some newlines clarity, and remove a logically dead allocation of shared info.
