* add esp-phy-lib submodule
* move libphy.a and phy_init.c from esp_wifi to esp_phy
* move librtc.a from esp_wifi to esp_phy
* move libbtbb.a from bt to esp_phy
* corresponding updates to build system

 The PHY initialization data is used for RF calibration.
 There are two ways to get the PHY initialization data.
 
-One is the default initialization data which is located in the header file :idf_file:`components/esp_wifi/{IDF_TARGET_PATH_NAME}/include/phy_init_data.h`.
+One is the default initialization data which is located in the header file :idf_file:`components/esp_phy/{IDF_TARGET_PATH_NAME}/include/phy_init_data.h`.
 
 It is embedded into the application binary after compiling and then stored into read-only memory (DROM).
 To use the default initialization data, please go to ``menuconfig`` and disable :ref:`CONFIG_ESP32_PHY_INIT_DATA_IN_PARTITION`.
