devres: add debug command to dump device resources
This new command can dump all device resources associated to
each device. The fields in every line shows:
- The address of the resource
- The size of the resource
- The name of the release function
- The stage in which the resource has been acquired (BIND/PROBE)
Currently, there is no driver using devres, but if such drivers are
implemented, the output of this command should look like this:
=> dm devres
- root_driver
- soc
- extbus
- serial@54006800
