[PATCH v4 2/6] clocksource/drivers: Add a new driver for the Atmel ARM TC blocks

Add a driver for the Atmel Timer Counter Blocks. This driver provides a clocksource and two clockevent devices. One of the clockevent device is linked to the clocksource counter and so it will run at the same frequency. This will be used when there is only on TCB channel available for timers.
