bb074904b4 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.

1c373cf293 adc: no longer support adc2 continuous mode on esp32c3 and esp32s3 
Due to HW limitation, we don't support this anymore. On s3 and 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.

81007ee4ed esp_adc: add adc ulp mode disable enum 
Prior to this commit, adc ulp is disabled by setting
adc_oneshot_unit_init_cfg_t::ulp_mode to false.

After this commit, a new enum `ADC_ULP_MODE_DISABLE` is added. So
setting `ulp_mode` to `ADC_ULP_MODE_DISABLE`, instead of `false`, to
disable the ulp mode.

facab8c5a7 tools: Increase the minimal supported CMake version to 3.16 
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.

d8a4b247b9 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.

6a0951ecb2 driver/adc: support for esp32s2 adc calibration scheme 
ESP32 lets the user choose from using Vref, Lookup Table, and Two-Point Calibration. In ESP32S2 only two-point calibration is supported. This commit support these changes in idf.

0c9e2c0fba esp_adc_cal/Remove lookup table 
This commit removes the lookup table mode due to inferior performance when compared
to linear mode under attenuation 0, 1 and 2. However small portions of the lookup table
are kept for the higher voltages of atten 3 (above ADC reading 2880). That voltage range
in atten 3 has non linear characteristics making the LUT performan better than linear mode.

2fceec4d85 feature(I2S-ADC): add ADC mode for I2S. 
1. Support built-in ADC for I2S.
2. Modify code of ADC, made no change to the original APIs.
3. Add APIs in I2S:
esp_err_t i2s_set_adc_mode(adc_unit_t adc_unit, adc1_channel_t adc_channel);
4. Add I2S ADC/DAC example code.
5. add old-fashion definition to make it more compatible
6. replase spi_flash_ APIs with esp_partition_ APIs
7. add example of generating audio table from wav
8. change example sound
