                If this option is enabled, NVS will be initialized and calibration data will be loaded from there.
                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.
                If unsure, choose 'y'.

                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.

                On some ESP targets, the USB PHY can interfere with WiFi thus lowering WiFi performance.
                As a result, on those affected ESP targets, the ESP PHY library's initialization will automatically
                disable the USB PHY to get best WiFi performance.
                This option controls whether or not the ESP PHY library will keep the USB PHY enabled on
                initialization.

                Note: This option can be disabled to increase WiFi performance. However, disabling this option will
                also mean that the USB PHY cannot be used while WiFi is enabled.

                to use the full calibration method. No calibration method is only used when the
