[PATCH v2] powerpc: add FHCI USB, FSL MCU, FSL UPM and GPIO LEDs bindings

[Anton Vorontsov]

This patch adds few bindings for the new drivers to be submitted through
the appropriate maintainers.

+Freescale QUICC Engine USB Controller
+
+Required properties:
+- compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb".
+- reg : the first two cells should contain usb registers location and
+  length, the next two two cells should contain PRAM location and
+  length.
+- interrupts : should contain USB interrupt.
+- interrupt-parent : interrupt source phandle.
+- fsl,fullspeed-clock : specifies the full speed USB clock source:
+  "none": clock source is disabled
+  "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+  "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+- fsl,lowspeed-clock : specifies the low speed USB clock source:
+  "none": clock source is disabled
+  "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+  "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+- hub-power-budget : USB power budget for the root hub, in mA.
+- gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
+  USBRN, SPEED (optional), and POWER (optional).

+Example:
+
+usb at 6c0 {
