IDF FreeRTOS uses vTaskSuspendAll()/xTaskResumeAll() to stop preemption on a particular core. However, those functions behave differently in FreeRTOS SMP. This commit replaces all calls of vTaskSuspendAll()/xTaskResumeAll() with vTaskPreemptionDisable()/vTaskPreemptionEnable() when compiling with SMP FreeRTOS.
See the spi_flash.rst in the programming guide folder for more details. The docs above is for the new SPI Flash API above 4.0, for legacy implementation (CONFIG_SPI_FLASH_USE_LEGACY_IMPL enabled), read README_legayc.rst in the same folder with this readme.
