xen: initialize platform-pci even if xen_emul_unplug=never
When xen_emul_unplug=never is specified on kernel command line reading files from /sys/hypervisor is broken (returns -EBUSY). It is caused by xen_bus dependency on platform-pci and platform-pci isn't initialized when xen_emul_unplug=never is specified. Fix it by allowing platform-pci to ignore xen_emul_unplug=never, and do not intialize xen_[blk|net]front instead.
