imx8mp imx_rpmsg_tty driver make Core-A crash

HI nxp
 
 I used imx_rpmsg_tty to create some virtual serial device in Core-A.
 
  Core-A will crash when Core-M reboot and virtual serial device is used. I will report log in browse file.
  It is because when the Core-M exits, the virtual serial device generated by the driver is being used, and the device node cannot be deleted and resources cannot be reclaimed. When restarting the Core-M it will attempt to generate a virtual serial port device again, but this virtual serial port device already exists, which will trigger this crash. Please solve it.
