The reset flags operation is selected by bit 2 in the "Reset and Load
Signals Decoders" register, not bit 1.

Hmm.  Given timing I'm not sure on the quickest route to upstream this.

Hence I'm going to take it via the togreg tree but might move it if the
merge window opens before I push that tree out other than as testing.

Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to play with it.

Thanks

Jonathan
