Jim Mussared b4236c7368 stm32: Rename pin_obj_t to machine_pin_obj_t.
This is now consistent with other ports.

Also renamed `pin_{board/cpu}_pins_locals_dict` to
`machine_pin_{board/cpu}_pins_locals_dict`.

This work was funded through GitHub Sponsors.

Damien George 95d8b5fd55 extmod/machine_adc: Factor ports' ADC Python bindings to common code.
No functional change, just code factoring to have the Python bindings in
one location, and all the ports use those same bindings.

Rene Straub 72ef2e6291 stm32/machine_adc: Fix and improve STM32H5 support.
Changes are:
- Run ADC on PCLK/16.
- Verify and optimize timings (ADC_STAB_DELAY_US, ADC_SAMPLETIME_DEFAULT).
- Add support for STM32H5 VBAT and COREVDD channels on ADC2.
- Replace ADC constants in machine_adc_locals_dict_table.
- Convert STM32 literal to channel numbers in adc_config_channel with
  corresponding STM32 LL library functions (__LL_ADC_IS_CHANNEL_INTERNAL(),
  __LL_ADC_CHANNEL_TO_DECIMAL_NB()).

Reasoning for the second last point: the STM32 driver literals are uint32_t
that don't work with MP_ROM_INT() which handles signed 31 bit integers
only.  Introduce enumerator machine_adc_internal_ch_t to define external
channels (0..19), internal channels (256..) and the special channel VREF
(0xffff).  Values are converted to STM32 literals with adc_ll_channel()
when required in adc_config_and_read_u16().

Yuuki NAGAO cb38f77918 stm32/adc: Add workaround for ADC errata with G4 MCUs.
For STM32G4, there is a errata on ADC that may get wrong ADC result.
According to the errata sheet, this can be avoid by performing two
consecutive ADC conversions and keep second result.

Jim Mussared 94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

Jim Mussared 0e7bfc88c6 all: Use mp_obj_malloc everywhere it's applicable.
This replaces occurences of

    foo_t *foo = m_new_obj(foo_t);
    foo->base.type = &foo_type;

with

    foo_t *foo = mp_obj_malloc(foo_t, &foo_type);

Excludes any places where base is a sub-field or when new0/memset is used.

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.

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.
