There were several different spellings of MicroPython present in comments,
when there should be only one.

<title>stmhal: Implement delayed RTC initialization with LSI fallback.</title>

<id>urn:sha1:86aa16bea61da8a8d156a7a928902a0bf4c85b73</id>
<content type='text'>
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.

<id>urn:sha1:9e8eba797e250d808bca7807ef7dd44e23a56a5b</id>
<content type='text'>
The DFU bootloader on the ST32F7 chip changes the clocksource
for various possible boot sources (UART1, UART3, I2C1-3).
This commit resets those clock sources back to their cold
reset values.
