net: Fix problem with 405EZ ethernet interrupt
On 405EZ the RX-/TX-interrupts are coalesced into one IRQ bit in the UIC. We need to acknowledge the RX-/TX-interrupts in the SDR0_ICINTSTAT reg as well. This problem was introduced with commit d1631fe1 [ppc4xx: Consolidate PPC4xx UIC defines] Signed-off-by: James Clough <james@rtetc.com> Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
