adc: no longer support adc2 oneshot mode on esp32c3
...
Due to HW limitation, we don't support this anymore. On c3, ADC2 under oneshot mode is not stable.
However, you can enable CONFIG_ADC_ONESHOT_FORCE_USE_ADC2_ON_C3 to force use
ADC2.

adc: no longer support adc2 continuous mode on esp32c3
...
Due to HW limitation, we don't support this anymore. On c3, ADC2 under continuous mode is not stable.
However, you can enable CONFIG_ADC_CONTINUOUS_FORCE_USE_ADC2_ON_C3_S3 to force use
ADC2.

Also:
1. Separate static configuration into init phase to improve
performance
2. Add a init code config layer to avoid duplicated configuration
3. Add a HW_CALIBRATION_V1 caps

adc_digi: update_adc_api_for_5M_freq_limit
...
The ``adc_digi_config_t`` struct is modified on esp32c3: configuration
of clock divider factors are not provided anymore. The SARADC sampling
frequency is provided instead. In this way, we can handle the frequency
limit better.

driver: Add adc_digi single conversion mode
...
- add lock for single read and continuous read APIs
- update onetime read start singal delay for hardware limitation[*]
- move adc_caps to soc_caps.h
- update license dates
[*] There is a hardware limitation. If the APB clock frequency is high, the
step of this reg signal: ``onetime_start`` may not be captured by the
ADC digital controller (when its clock frequency is too slow). A rough
estimate for this step should be at least 3 ADC digital controller
clock cycle.
