Damien George fef2114404 stm32/uart: Fix LPUART1 baudrate set/get.
It needs to use a different function because the formula to compute the
baudrate on LPUART1 is different to a normal UART.

Fixes issue #7466.

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 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 f96f53cd97 stm32/boards: Add stm32??xx_hal_conf_base.h files with common settings.
These are intended to be used by all boards, to reduce the size of a
board's configuration.
