Update extcon for v5.2

Detailed description for this pull request:
1. Add new extcon-intel-mrfld.c extcon provider driver
- On Intel Merrifield the Basin Cove PMIC provides a feature to detect
the USB connection type. This driver utilizes the feature in order
to support the USB dual role detection.

2. Update the extcon provider drivers
- For extcon-intel-cht-wc.c, make charger detection co-existed
  with OTG host mode and enable external charger.
- For intel extcon driver, add common header file (extcon-intel.h)
  in order to remove the duplicate definitions.
- For extcon-arizonal.c, disable microphone detection on driver removal.

3.
- Edit comment of extcon_unregister_notifer() to fix a build warning
- Add CONFIG_ACPI dependency to Kconfig to fix a build error for extcon-axp.c
