Jaiber John	d7b938f857	ish: Add support for ISH chip ... This patch adds the initial support for ISH chip to enable the EC firmware to boot on Intel Integrated Sensor Hub (ISH). The following are enabled: 1. Inter-Processor Communication (IPC) driver that enables the ISH to communicate with the host Operating system via shared registers. 2. High Precision Event Timer (HPET) driver that provides configurable timers for the FW to use in task scheduling. 3. I2C bus driver for accessing sensors. 4. UART console driver with TX support only.
