Detailed description for patchset:
1. Add new Richtek RT8973A extcon driver
This driver support for Richtek RT8973A which is Micro USB Switch OVP and
i2c interface. The RT8973A is a USB port accessory detector and switch that is
optimized to protect low voltage system from abnormal high input voltage
(up to 28V) and supports high speed USB operation. Also, RT8973A support
'auto-configuration' mode. If auto-configuration mode is enabled, RT8973A
would control internal h/w patch for USB D-/D+ switching.
