[PATCH] ARM: clocksource: moxart: documentation: update device tree bindings document

1. describe compatible variable "Must be" instead of "Should be".
2. change description so it's from the point of view of the device

Notes:
    Hi Daniel,
    
    The device tree bindings document (already merged) needs another update.
    
    Can be applied directly to timers/clockevents-next.
    
    Best regards,
    Jonas
