staging: pi433: add debugfs interface
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.
