pin PC7 is an alias for z1_uart_pin

I had to change some stepper settings and after changing the appropriate parameters I have this message Klipper reports: ERROR pin PC7 is an alias for z1_uart_pin Once the underlying issue is corrected, use the "RESTART" command to reload the config and restart the host software.
