hid: Import iichid - I2C transport backend for HID subsystem
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).
