Bootloader makefile that can be used for different ESP32x variants
Updates `cpu/esp_common/periph/flash` for ESP-IDF 4.4. `spi_flash_*` functions for ESP32 are removed since these functions are now used from ESP-IDF. DEBUG output are changed to be platform independent.
The MCU_* conditionals are inverted so that they can be tested for ESP8266. In all other cases the MCU is any ESP32x SoC
Implements an interface for ESP-IDF types and functions that are required by RIOT-OS but cannot be included directly due to name conflicts.
periph/spi implementation can be used for ESP8266 only from now. An implementation using the ESP-IDF spi HAL interface is required for ESP32x SoCs.
