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.
