yet).

rtc implementation
Basic rtc implementation. LSE oscillator is used as clock source
(32kHz). Second (periodic) interrupt is enabled to trigger a interrupt
every second. RTC is not calibrated with tamper pin (so could be off
with a few second each month). Added small uptime cmd.

No changes to buspeeds. Adaptions to UART baud rates.
