ffb2db586a 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.

Refer to errata to know more details:
