esp32: uart deinit missing
Hello,
I was trying to start internet connection using GSM module and run into some troubles. A part from network.PPP stability there is kind a device restarts when comunicating with modem over serial after network.PPP link is deactivated, https://github.com/micropython/micropython/issues/4708 so I decided to deinit uart and init it again with hope it gonna solve that issue,but for my surprise uart.deinit is not available.
