clocksource: Add Marvell Orion SoC timer
This patch add a DT enabled driver for timers found on Marvell Orion SoCs (Kirkwood, Dove, Orion5x, and Discovery Innovation). It installs a free- running clocksource on timer0 and a clockevent source on timer1. Corresponding device tree documentation is also added.
