clocksource/drivers/timer-ti-dm: Move struct omap_dm_timer fields to driver

There is no longer any need to expose the elements of struct omap_dm_timer
outside the driver. 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.

clocksource/drivers/timer-ti-dm: Implement cpu_pm notifier for context save and restore

omap_dm_timer_enable() restores the entire context(including counter)
based on 2 conditions:
- If get_context_loss_count is populated and context is lost.
- If get_context_loss_count is not populated update unconditionally.

Case2 has a side effect of updating the counter register even though
context is not lost. When timer is configured in pwm mode, this is
causing undesired behaviour in the pwm period.

Instead of using get_context_loss_count call back, implement cpu_pm
notifier with context save and restore support. And delete the
get_context_loss_count callback all together.
