dpaa: Mark BMan and QMan as earlier driver modules

Browse Source 
The BMan softc must exist when dtsec devices are created, else a NULL
pointer is dereferenced.  QMan likely as well.  Until now, we have relied on
order within the fdt parsing to attach correctly, but this obviously is not
foolproof.  Mark these as BUS_PASS_SUPPORTDEV so they're probed and attached
explicitly before dtsec devices.
