hid: Import iichid - I2C transport backend for HID subsystem

2021-01-07T23:18:43Z

This implements hid_if.m methods for HID-over-I2C protocol [1]. Following kernel options are added: IICHID_SAMPLING - Enable support for a sampling mode as interrupt resource acquisition is not always possible in a case of GPIO interrupts. IICHID_DEBUG - Enable debug output. The module is based on prior Marc Priggemeyer work (D16698).
