USB: xhci: Support xHCI host controllers and USB 3.0 devices.

This is the first of many patches to add support for USB 3.0 devices and
the hardware that implements the eXtensible Host Controller Interface
(xHCI) 0.95 specification.  This specification is not yet publicly
available, but companies can receive a copy by becoming an xHCI
Contributor (see http://www.intel.com/technology/usb/xhcispec.htm).

No xHCI hardware has made it onto the market yet, but these patches have
been tested under the Fresco Logic host controller prototype.

This patch adds the xHCI register sets, which are grouped into five sets:
 - Generic PCI registers
 - Host controller "capabilities" registers (cap_regs) short
 - Host controller "operational" registers (op_regs)
 - Host controller "runtime" registers (run_regs)
 - Host controller "doorbell" registers

These some of these registers may be virtualized if the Linux driver is
running under a VM.  Virtualization has not been tested for this patch.
