xen: enable platform-pci only in a Xen guest
While debugging kexec issues in a PVonHVM guest I modified
xen_hvm_platform() to return false to disable all PV drivers. This
caused a crash in platform_pci_init() because it expects certain data
structures to be initialized properly.
To avoid such a crash make sure the driver is initialized only if
running in a Xen guest.
