The pwm and remoteproc drivers just use struct omap_dm_timer as a cookie. Let's move the elements of struct omap_dm_timer into struct dmtimer that is private to the driver. To do this, we mostly rename omap_dm_timer to dmtimer in the driver. We keep omap_dm_timer only for the exposed functions in the platform_data for the pwm and remoteproc drivers. Let's also add a note about not using the exposed functions internally as those will get deprecated eventually in favor of Linux generic frameworks.
