Damien George d2a34c62e7 stm32/uart: Add uart_set_baudrate function.
This allows changing the baudrate of the UART without reinitialising it
(reinitialising can lead to spurious characters sent on the TX line).

Damien George 0efa0b5437 stm32/mboot: Add ELEM_TYPE_STATUS element so application can get status.
This new element takes the form: (ELEM_TYPE_STATUS, 4, <address>).  If this
element is present in the mboot command then mboot will store to the given
address the result of the filesystem firmware update process.  The address
can for example be an RTC backup register.

Damien George cc2a35b7b2 stm32/rtc: Validate the RTC prescaler on boot and change if incorrect.
Devices with RTC backup-batteries have been shown (very rarely) to have
incorrect RTC prescaler values.  Such incorrect values mean the RTC counts
fast or slow, and will be wrong forever if the power/backup-battery is
always present.

This commit detects such a state at start up (hard reset) and corrects it
by reconfiguring the RTC prescaler values.

Damien George 0118c07916 stm32/machine_adc: Fix ADC auto-calibration to run when ADC not enabled.
Prior to this commit, the ADC calibration code was never executing because
ADVREGEN bit was set making the CR register always non-zero.

This commit changes the logic so that ADC calibration is always run when
the ADC is disabled and an ADC channel is initialised.  It also uses the LL
API functions to do the calibration, to make sure it is done correctly on
each MCU variant.
