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.

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.
