xhci: Platform updates, 64-bit DMA, and trace events for 3.12.

Hi Greg,

This pull request includes one new feature for the xhci-plat driver (device
tree support).  Felipe was fine with the patch last I checked, but hadn't
provided an official Acked-by line.

This pull request also includes 13 patches from my FOSS Outreach Program for
Women (OPW) intern, Xenia.  She fixed a bug in the xHCI driver so that the
driver can allocate 64-bit consistent DMA, converted the driver to use dynamic
debugging, and added a bunch of new trace events for the xHCI driver.  The
python plugin for trace-cmd should be up on git hub shortly, although the trace
events are usable without it.

I'm very happy with the progress that Xenia has made, and I look forward to her
future contributions to the Linux kernel.

+USB xHCI controllers
+
+Required properties:
+  - compatible: should be "xhci-platform".
+  - reg: should contain address and length of the standard XHCI
+    register set for the device.
+  - interrupts: one XHCI interrupt should be described here.
+
+Example:
+	usb@f0931000 {
+		compatible = "xhci-platform";
+		reg = <0xf0931000 0x8c8>;
+		interrupts = <0x0 0x4e 0x0>;
+	};
