Allow by-path addressing when flashing Klipper firmware #696
Description
Is your feature request related to a problem? Please describe
Context: using multiple 32-bit Creality boards, both in multi-instance installations and in multi-mcu configurations, where Creality used CH431 ICs rather than native USB. E.g. v4.x, Ender 3 S1, etc: these all enumerate to the same by-id string, " /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 ".
Issue: when attempting to flash firmware using the KIAUH options to make use of stm32flash, when it comes time to select the board to flash only one device will be listed (the most-recently-plugged-in device) because by-id addressing is used.
Describe the solution you'd like
"ls /dev/serial/by-id/" will list only one entry in the CH431 format (" /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 ") when multiple boards are connected to the host, but "ls /dev/serial/by-path/" will list additional entries for each board. "Ls /dev/serial/*" will show both lists.
For instances where the magic string " /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 " is found allow the user to select by-path addressing to select the board they want to flash. Include suitable warnings as required.
Describe alternatives you've considered
Alternatively, allow by-path addressing as an option regardless of whether the magic string is found.
