toshiba_bluetooth: Clean up *_add function and disable BT device at removal
This patch cleans the toshiba_bluetooth_add function by using the
recently introduced function toshiba_bluetooth_present, simplifying
its code and returning appropriate error values.
Also, disables the BT device at the removal of the driver, by using
the function toshiba_bluetooth_disable.
