fix(adc): rename ADC_ATTEN_DB_11 to ADC_ATTEN_DB_12
By design, it's 12 dB. There're errors among chips, so the actual
attenuation will be 11dB more or less

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.
Refer to errata to know more details:
