This adds debugfs interface that can be used for debugging possible hardware/software issues. It currently exposes the following debugfs entries for each SPI device probed: /sys/kernel/debug/pi433/<DEVICE>/regs ... The 'regs' file contains all rf69 uC registers values that are useful for troubleshooting misconfigurations between 2 devices. It contains one register per line so it should be easy to use normal filtering tools to find the registers of interest if needed.
