This commit refactors SOC_USB_PERIPH_NUM as follows:
- Renamed to SOC_USB_OTG_PERIPH_NUM to avoid confusion with USB Serial JTAG
- Updated to unsigned integer "1U"
- Updated some build rules to depend on SOC_USB_OTG_SUPPORTED instead
Closes: https://github.com/espressif/esp-idf/issues/9208
When I2S is configured into different modes, the slot sequence varies.
This commit updates slot sequence tables and corresponding descriptions
in (both code and programming guide).
