Update extcon for 4.5

Detailed description for patchset:
 1. Add new MAX3355 extcon driver
 - Maxim Integrated MAX3355E chip integrates a charge pump
   and comparator to enable a system with an integrated
   USB OTG dual-role transceiver to function as an USB OTG
   dual-role device.
 
 2. Update the extcon-arizona driver for jack detection
 - Add the device binding for the jack detection and add
   the documentation of extcon-arizona.c.
 
 3. Fix the minor issue of extcon driver
 - Add IRQF_ONESHOT to interrupt flags of extcon-rt8973.
 - Fix the return value regmap_irq_get_virq() of
   extcon-max(14577|77693|77843).c driver by using script[1].

Maxim Integrated MAX3355 USB OTG chip
-------------------------------------
MAX3355 integrates a charge pump and comparators to enable a system with an
integrated USB OTG dual-role transceiver to function as a USB OTG dual-role
device.
Required properties:
- compatible: should be "maxim,max3355";
- maxim,shdn-gpios: should contain a phandle and GPIO specifier for the GPIO pin
connected to the MAX3355's SHDN# pin;
- id-gpios: should contain a phandle and GPIO specifier for the GPIO pin
connected to the MAX3355's ID_OUT pin.
Example:
usb-otg {
compatible = "maxim,max3355";
maxim,shdn-gpios = <&gpio2 4 GPIO_ACTIVE_LOW>;
id-gpios = <&gpio5 31 GPIO_ACTIVE_HIGH>;
};
