1f055d28b8 Driver update: I2S pdm and built-in DAC
1. Modify I2S DAC built-in mode settings
2. Add I2S pdm mode
3. Correct I2S signal index in full-duplex mode
4. Modify dac output function
5. Add dac pad init functions
6. Modify DAC documentation
7. Add i2s_set_dac_mode API

fc1ee2666a I2S: fixed support for 24 and 32-bits, fixed tx/rx at the same time and others in log:
Add support 24, 32 bits

@jxmao optimize i2s_zero_buffer

@jxmao correct config support slave mode

@jxmao correct setup pin support tx/rx at the same time

Enhance pin power

@jxmao add dynamic change number of channels

remove nvs_init

remove start log and enhance power pin setup

using enum for i2s_channel and i2s_bits_per_sample, return ESP_ERR_INVALID_ARG when check params

validate i2s_bits_per_sample and channel

check tx & rx buffer before fill zero

remove checking channel as @jxmao suggest

limit dma buffer

modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512

Add support 24, 32 bits

reduce push function

Modify sample can test with 24, 32-bits

Add i2s sample README

Fixed i2s_set_clk got reset sometime

can changes bit-wide while running

Fix sample rate calculation for DAC mode from @jeroen

modify example can change bits per sample every 5 seconds

cleanup

add comment for bytes_per_sample

update as @angus suggestions

Add i2s_set_clk api

I2S driver bug fixed as following log:

@jxmao optimize i2s_zero_buffer

@jxmao correct config support slave mode

@jxmao correct setup pin support tx/rx at the same time

Enhance pin power

@jxmao add dynamic change number of channels

remove nvs_init

remove checking channel as @jxmao suggest

limit dma buffer

modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512

limit dma buffer to 4092

change gpio_matrix_*_check to inline function, remove some comments and rename test_i2s function to setup_triangle_sine_waves
