[PATCH 05/43] OvmfPkg/README: bump minimum QEMU version to 1.7.1, machine types to 1.7

["Laszlo Ersek" <lersek@redhat.com>]

Due to switching to the QemuFwCfgAcpiPlatformDxe driver earlier in this
series, require QEMU version 1.7.1 in the "OvmfPkg/README" file, and
require 1.7 or later machine types too.
