Adds AMBA driver for ARM Coresight Cross Trigger Interface (CTI) driver and device-tree binding for CTI module. I have tested the driver on an OMAP4430 device and include the relevant patches needed to enable CTI on OMAP4 devices for reference. I would like to get some feedback on the binding, CTI APIs and usage of the APB clock for OMAP4. I have seen that there has been some recent discussion around adding other coresight drivers for ARM devices [1] and so it would be also good to align on the appropriate location for coresight drivers in general. This series is based on the ARM-SOC for-next branch and Will Deacon's patch for the CTI lock registers [2].
