Revert "xen: start PCI hole at 0xe0000000 (same as pc_init1 and qemu-xen-traditional)"
This reverts commit 9f24a8030a70ea4954b5b8c48f606012f086f65f. 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. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
