Hey Hans & Mauro,

this patch enables polling with an HRtimer on the Wave5 Codec, the
change is needed because a new hardware emerged with a defective
interrupt line. I have investigated whether a general fake IRQchip could
be implemented for this use case, but it turned out to be not practical
on a general level and on a specific level with a number of
difficulties.

Please pull this change.
