During the review of I2C controller driver, Andreas pointed out that
we should use Owl instead of OWL in all places and also Actions should
be replaced by Actions Semiconductor. So, please change it in relevant
places. For this binding, title should be:

Actions Semiconductor Owl SoC's Clock Management Unit (CMU).
