Enable f4 discovery (#4913)

* scripts specify exact hardware CI device

* proteus serial number

* dropped this: |

* read envionment variable for correct port

* it's lowercase for whatever reason

* d'oh

* uncomment

* s

* f4 discovery serial numbers

* s

* debug mode openocd

* is that really the serial number?

* tolerate no SPI device

* remove debug flag

* kick to make sure machine still alive after move
