fix(console): switch USB PHY to OTG when OTG is used for console

Browse Source 
On ESP32-S3 with the default efuse settings, USB PHY is connected to
the USB_SERIAL_JTAG peripheral. If USB OTG peripheral is used for the
console, we need to additionally switch the PHY to USB OTG, otherwise
we won't get any output.
