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.

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.
