   The uart1 is found be in reset state, and the sysclk is not enabled for it.
   
   ## Summary
   
   When enable `CONFIG_ESP32S2_UART1` and connect an external usb-uart 
converter to UART1(TXPIN=17,RXPIN=18), it's found that the host can't 
communicate with the esp32s2 board.
   
   ## Impact
   
   esp32s2, uart1
   
   ## Testing
   
   enable `CONFIG_ESP32S2_UART1`, connect an external usb-uart converter to 
UART1(TXPIN=17,RXPIN=18) to test.
   
   1. board send
   run this command on the board, and observe data on host machine (in another 
minicom)
   ```
   nsh> echo abc >/dev/ttyS1
   ```
   2. board receive
   run this command on the board, and press some keys on host machine (in 
another minicom) to send
   ```
   nsh> cat /dev/ttyS1 &
   ```
