clocksource: Workaround the hpet fallback problem
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2017164
MR: !159 (merged)
The first patch is fixing HPET problem on some Intel system that may cause problem. Patch 2 is a RHEL only patch to temporarily increase the WATCHDOG_MAX_SKEW threshold to avoid triggering hpet fallback problem. It will be reverted once the official upstream patch that address the problem is backported.
