[MIPS] Sibyte: Delete {sb1250,bcm1480}_steal_irq().
They break the timer interrupt initialization and only seem to be a kludge for initialization happening in the wrong order. Further testing done by Thiemo confirms the suspicion that the other invocations also seem to have useless. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
