Detach selected devices from kernel usage

Remove detached device nodes from the kernel's device tree

Direct OBP to delete all detached nodes from its device tree

For DR Attach, dr_daemon(1M) executes ioctl(2) calls to:

Convert the proto nodes to CF1 nodes

The pathname of the device node is /devices/pseudo/dr@0:0.
