NVIDIA: SAUCE: clocksource: timer-tegra186: adjust WDT timing

Browse Source 
This change disables WDT later on suspend and enables WDT earlier on
resume. By extending the coverage of WDT, system crashes caused by
drivers in their suspend()/suspend_late() and resume_early()/resume()
callbacks leads to a power-on reset instead of hanging forever.
