clocksource/drivers/timer-ti-dm: Save and restore timer TIOCP_CFG
As we are using cpu_pm to save and restore context, we must also save and
restore the timer sysconfig register TIOCP_CFG. This is needed because
we are not calling PM runtime functions at all with cpu_pm.
Fixes: b34677b0999a ("clocksource/drivers/timer-ti-dm: Implement cpu_pm notifier for context save and restore")
