hw/usb/hcd-xhci: Reset the XHCIState with device_cold_reset()

Currently the hcd-xhci-pci and hcd-xhci-sysbus devices, which are
mostly wrappers around the TYPE_XHCI device, which is a direct
subclass of TYPE_DEVICE.  Since TYPE_DEVICE devices are not on any
qbus and do not get automatically reset, the wrapper devices both
reset the TYPE_XHCI device in their own reset functions.  However,
they do this using device_legacy_reset(), which will reset the device
itself but not any bus it has.

Switch to device_cold_reset(), which avoids using a deprecated
function and also propagates reset along any child buses.
