Move hardware-specifics (pin assignments, power management) to hwconfig_*.py. The build system will build a firmware image firmware-filesystem-$variant.uf2 for all variants for which a hwconfig_$variant.py file exits. Inside the filesystem image, the selected variants hwconfig_$variant.py file will always be named hwconfig.py. At runtime, main.py will attempt to import hwconfig which will load the configuration for the correct variant. Currently, the hwconfig_* modules are expected to define the pin mapping and implement a board_init method. Signed-off-by: Matthias Blankertz <matthias@blankertz.org>
