c2e424e7af ulp: fix calculation or ulp_run argument
The argument to ulp_run should be expressed in 32-bit words. Both the
address of ulp_entry and RTC_SLOW_MEM already are uint32_t*, so their
difference is the difference in addresses divided by sizeof(uint32_t).
Therefore the extra division by sizeof(uint32_t) is not needed.

af6cfc5552 docs, examples: use rtc_gpio_isolate to disconnect GPIO12
This is needed to reduce deep sleep current on ESP32-WROVER modules.

Ref TW18165.

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

7abd9bc023 ULP: remove deprecated cycle_sel field from ADC instruction
Cycle_sel field was never used in binutils and was always set to zero.
This change removes it from documentation and examples.

Needs ULP binutils with this change:
