2015-11-23stmhal: Implement delayed RTC initialization with LSI fallback.T S
If RTC is already running at boot then it's left alone. Otherwise, RTC is started at boot but startup function returns straight away. RTC startup is then finished the first time it is used. Fallback to LSI if LSE fails to start in a certain time. Also included: MICROPY_HW_CLK_LAST_FREQ hold pyb.freq() parameters in RTC backup reg MICROPY_HW_RTC_USE_US option to present datetime sub-seconds in microseconds MICROPY_HW_RTC_USE_CALOUT option to enable RTC calibration output CLK_LAST_FREQ and RTC_USE_CALOUT are enabled for PYBv1.0.

pyb module still has pyb.delay and pyb.udelay, but these now point to time.sleep_ms and time.sleep_us respectively.
