mpc83xx: mpc8313 - handle erratum IPIC1 (TSEC IRQ number swappage)
mpc8313e erratum IPIC1 swapped TSEC interrupt ID numbers on rev. 1 h/w (see AN3545). The base device tree in use has rev. 1 ID numbers, so if on Rev. 2 (and higher) h/w, we fix them up here. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Reviewed-by: Roland Lezuo <roland.lezuo@chello.at>
