xhci-platform: Change compatible string from xhci-platform to generic-xhci

This brings the xhci-platform bindings in sync with what we've done for
the ohci- and ehci-platform drivers. As discussed there using platform as a
postfix is a bit weird as the platform bus is a Linux specific thing and
the bindings are supposed to be OS agnostic.

Note that the old xhci-platform compatible string is kept around for, well,
compatibility reasons.

 USB xHCI controllers
 
 Required properties:
-  - compatible: should be "xhci-platform".
+  - compatible: should be "generic-xhci" (deprecated: "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";
+               compatible = "generic-xhci";
                reg = <0xf0931000 0x8c8>;
                interrupts = <0x0 0x4e 0x0>;
        };
