A couple minor improvements to spibus.c...

 - Change the description string to "SPI bus" (was "spibus bus").

 - This is the default driver for a SPI bus, not a generic implementation,
   so return the probe value that indicates such.

 - Use device_delete_children() at detach time, instead of a local loop
   to enumerate the children and detach each one individually.
