We don't need compatibility with 1.5 so we can simply
218e99
revert the patch creating it by default.
218e99
218e99
This patch:
218e99
 - reverts "pvpanic: create pvpanic by default for machine 1.5"
218e99
 - removes cannot_instantiate_with_device_add_yet flag
218e99

        hw/misc: don't create pvpanic device by default
218e99
218e99
        This patch is based on Hu Tao's:
218e99
        http://lists.nongnu.org/archive/html/qemu-devel/2013-08/msg00124.html
218e99
218e99
        No need to hard-code pvpanic as part of the machine.
218e99
        It can be added with "-device pvpanic" from command line (The next patch).
218e99
        Anyway, for backport compatibility it is still part of 1.5
218e99
        machine.
