yinshengkai 9c6f48e57b drivers/segger: add RTT serial support
usage:
  1. Connect Jlink, start JLinkGDBServer
     JLinkGDBServer -if SWD -device stm32h743zi -speed 16000
  2. Listen to the RTT port data and forward it to the virtual serial port
     sudo socat -d -d PTY,link=/dev/ttyRTT0,raw,ignoreeof TCP:127.0.0.1:19021,reuseaddr
  3. Read serial data
     minicom -D /dev/ttyRTT0
