Update extcon for 4.16

Detailed description for this pull request:
1. Add support to notify USB connector for "ChromeOS Embedded Controller".
- extcon-usbc-cros-ec driver detects the EXTCON_USB and EXTCON_USB_HOST
  connector type and then notify the state/properties to the consumer device.

2. Update the detection on probe time and clean-up code for "X-Power AXP288".
- Detect the state of connector after a couple of seconds after probe()
  becasue extcon-axp288.c driver depends on other device driver like mux.
  In order to guarantee the correct state, the extcon-axp288.c uses the
  delayed_work.
- Set EXTCON_CHG_USB_SDP type as the safe default type if unknown connector
  is attached because the data sheet of axp288 doesn't handle
  the all exception cases.
- Remove unused code

3. Fix the minor issue of extcon driver
- Fix platform get_irq's error checking for extcon-adc-jack.
- Delete unneeded initialization for extcon-max8997/max77693.
