feat(esp8266): Add phy init data in code

Not support to config phy_init_data now, and need real code to use this data.

+        PHY calibration will be skipped on deep sleep wakeup. If calibration data is not found, full calibration
+        will be performed and stored in NVS. Normally, only partial calibration will be performed. 
+        If this option is disabled, full calibration will be performed.
+
+        If it's easy that your board calibrate bad data, choose 'n'.
+        Two cases for example, you should choose 'n':
+        1.If your board is easy to be booted up with antenna disconnected.
+        2.Because of your board design, each time when you do calibration, the result are too unstable.

+        When using a custom partition table, make sure that PHY data
+        partition is included (type: 'data', subtype: 'phy').
+        With default partition tables, this is done automatically.
+        If PHY init data is stored in a partition, it has to be flashed there,
+        otherwise runtime error will occur.
+
+        If this option is not enabled, PHY init data will be embedded
+        into the application binary.
