elog: Use the RTC driver interface instead of reading CMOS directly.

Use the RTC driver interface to find the timestamp for events instead of
    reading the CMOS based RTC directly on x86 or punting on ARM. This makes
    timestamps available on both architectures, assuming an RTC driver is
    available.

BUG=None
    TEST=Built and booted on nyan_big and link and verified that the timestamps
    in the event log were accurate.
