treewide: add USB OTG support for hammerhead

This patch set adds USB OTG support for the LG Nexus 5 (hammerhead) phone. My only question is related to patch #4 where the GPIO support is added to bq24190_charger. Based on the information in the device tree binding Documentation/devicetree/bindings/power/supply/bq24190.txt, I should be using a gpio-hog. I'm not sure what my input pin would be for this particular board since I can't find a publicly-available datasheet for this board. The USB OTG support works properly with this patch set. I am able to use USB networking, and I'm also able to plug in a USB hub with a thumb drive on the phone, and mount the drive. All of the other msm8974-based boards in upstream use the qcom,pm8941-charger (via the smbb node) that is defined in qcom-pm8941.dtsi. USB networking works for me with that driver, however I'm not able to get any devices connected to my USB hub to show up on the phone, even when I port the GPIO code into that driver. I can see the USB hub node with lsusb, but no devices on the hub. Thanks in advance for any assistance that you can provide.
