USB: xhci: BIOS handoff and HW initialization.
Add PCI initialization code to take control of the xHCI host controller
away from the BIOS, halt, and reset the host controller. The xHCI spec
says that BIOSes must give up the host controller within 5 seconds.
Add some host controller glue functions to handle hardware initialization
and memory allocation for the host controller. The current xHCI
prototypes use PCI interrupts, but the xHCI spec requires MSI-X
interrupts. Add code to support MSI-X interrupts, but use the PCI
interrupts for now.
