tboot: fix tboot memory mapping for 32b

This patch used fixmap to get TXT heap base/size and SINIT base/size
from TXT pub config registers (whose address starts from 0xfed20000),
and get DMAR table copy from TXT heap (whose address may start from
0x7d520000) for tboot, instead of using map_pages_to_xen(), which will
cause panic on x86_32.
