Revert "xen: start PCI hole at 0xe0000000 (same as pc_init1 and qemu-xen-traditional)"

Browse source 
This reverts commit 9f24a8030a.

The start of the PCI hole is actually set to 0xf0000000 by hvmloader.
In order to retain ABI compatibility with Xen we leave the start of the
PCI hole at 0xf0000000 in QEMU (for Xen) too.
