rtc: Add an RTC API, and implement it for x86.

This CL adds an API for RTC drivers, and implements its two functions,
    rtc_get and rtc_set, for x86's RTC. The function which resets the clock when the
    CMOS as lost state now uses the RTC driver instead of accessing the those
    registers directly.

BUG=None
    TEST=Built and booted on Link with the event log code modified to use
    the RTC interface. Verified that the event times were accurate.
