accel/qaic: Add QAIC_DETACH_SLICE_BO IOCTL
Once a BO is attached with slicing configuration that BO can only be used
for that particular setting. With this new feature user can detach slicing
configuration off an already sliced BO and attach new slicing configuration
using QAIC_ATTACH_SLICE_BO.
This will support BO recycling.
detach_slice_bo() detaches slicing configuration from a BO. This new
helper function can also be used in release_dbc() as we are doing the
exact same thing.
