Herwin Grobben 8f68e26f79 stm32: Add support for G4 MCUs, and add NUCLEO_G474RE board defn. 
This commit adds support for the STM32G4 series of MCUs, and a board
definition for NUCLEO_G474RE.  This board has the REPL on LPUART1 which is
connected to the on-board ST-link USB-UART.

Jan Staal 9e2423e730 stm32: Add support for H7A3(Q)/H7B3(Q), and STM32H73B3I_DK board defn. 
This commit is based upon prior work of @dpgeorge and @koendv.

MCU support for the STM32H7A3 and B3 families MCUs:
- STM32H7A3xx
- STM32H7A3xxQ (SMPS)
- STM32H7B3xx
- STM32H7B3xxQ (SMPS)

Support has been added for the STM32H7B3I_DK board.

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 ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate. 
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size
on most ports:

Chris Mason 0096041c99 stm32/{adc,machine_adc}: Change ADC clock and sampling time for F0 MCUs. 
STM32F0 has PCLK=48MHz and maximum ADC clock is 14MHz so use PCLK/4=12MHz
to stay within spec of the ADC peripheral.  In pyb.ADC set common sampling
time to approx 4uS for internal and external sources.  In machine.ADC
reduce sample time to approx 1uS for external source, leave internal at
maximum sampling time.
