Place non-ISR ringbuf functions (like xRingbufferSendFromISR/xRingbufferReceiveFromISR) into flash.
Place ISR ringbuf functions (like xRingbufferSendFromISR/xRingbufferReceiveFromISR) into flash.
This frees up IRAM, but the functions can no longer be called when the cache is disabled
or from an IRAM interrupt context.
This option is not compatible with ESP-IDF drivers which is configured to run the ISR from an IRAM context,
e.g. CONFIG_UART_ISR_IN_IRAM.
