input: Add ChromeOS EC keyboard driver
Use the key-matrix layer to interpret key scan information from the EC and inject input based on the FDT-supplied key map. This driver registers itself with the ChromeOS EC driver to perform communications. The matrix-keypad FDT binding is used with a small addition to control ghosting.
