Add support for integrated tamper detection function in both PCF2127 and PCF2129 chips. This patch implements the feature by adding an additional timestamp0 file to sysfs device path. This file contains seconds since epoch, if an event occurred, or is empty, if none occurred. Interface should match ISL1208 and RV3028 RTC drivers. Signed-off-by:
