Damien George e58848a21e alif/machine_rtc: Implement RTC.datetime to get and set the RTC. 
The LPRTC peripheral is a 32-bit counter with a 16-bit prescaler.  It's
configured here to count at 1Hz (to get maximum date range) and then the
prescaler value is used to get 30 microsecond resolution.  That's
essentially a 32+15=47-bit counter.
