Provide the possibility to allow users to synchronize the RTC. It is (still) disabled by default, since certain combinations of linux kernel version and hardware pieces are subject to cause lockups. "rtcautotrim 10" and rtcfile have been favoured over "rtcsync" since "rtcsync" syncs the RTC every 11 seconds which is not necessary IMO. "rtcautotrim 10" will only set the time to the RTC if the gap between RTC and the system clock exceed more than 10 seconds. Change-Id: I2961bc554eb6caf6e6c78137a33c4fde256ae1ff
