clocksource/drivers/oxnas-rps: Add Oxford Semiconductor RPS Dual Timer
Add clocksource and clockevent driver from dual RPS timer. The HW provides a dual one-shot or periodic 24bit timers, the drivers set the first one as tick event source and the second as a continuous scheduler clock source. The timer can use 1, 16 or 256 as pre-dividers, thus the clocksource uses 16 by default.
