First sanity check, then expose the property.

First sanity check, then expose > the property. The slot number is already being checked at this point to ensure that it lies between NUBUS_FIRST_SLOT and NUBUS_LAST_SLOT (see the change to NUBUS_FIRST_SLOT in patch 4). Note that patch 4 also converts the range 0x9-0xf to the equivalent bitmask to ensure there should be no change in the available slots. ATB, Mark.

This prepares for allowing Nubus devices to be placed in a specific slot instead of always being auto-allocated by the bus itself.
