[v3,0/3] hw/usb: Always expect 'dma' link property to be set to simplify

Simplify the XHCI based devices by always passing a MemoryRegion
property to the device.  Doing so we can move the AddressSpace
field to the device struct, removing need for heap allocation.

Since v2:
- Use &error_abort (Eduardo)

Philippe Mathieu-Daudé (3):
  hw/pci: Introduce pci_dma_memory_region() helper
  hw/usb/hcd-xhci-pci: Abort if setting link property failed
  hw/usb/xhci: Always expect 'dma' link property to be set
