Why is this necessary? The interrupts were enabled for all
However, this patch is wrong as Jürgen mentioned, the SIER_FLAGS are
written to the SIER register after we enable the DMA enable bits which
leads to missing DMA enable bits at the end.
I created a new patch to cleanup the whole interrupt flag setup. I will
post it later.
