Raspberry Pi: Keep warnings from firmware in DT, if any
The /chosen/user-warnings property is created by the RPi firmware if
there are warnings to report, keep it to make debugging easier.
For example, if the firmware config.txt contains
"dtoverlay=error-example" and that example references an undefined
symbol "&nosuchdev" the warning can be read after boot:
$ cat /proc/device-tree/chosen/user-warnings
dterror: can't find symbol 'nosuchdev'
Failed to resolve overlay 'error-example'
