It's a good idea to reset the cpu before starting the main application
code. However it is difficult to reliably reset the cpu in software.
This changes the software to actually do a cpu hardware reset prior to
launching the main application - after each bootup the code checks to
see if the application should be started before entering the main
bootloader code. This helps ensure the application code is started in
a "pristine" cpu state.

Bring in the latest changes from Klipper. The STM32F4 variants are
still unsupported at this time.
