Looking at it one more time, we setup the GPDR with values from gpdr_lpm,
and afterwards we setup them once again to update for KEEP_CONFIG.
This can introduce a kind of spike on the GPIO (depending on how fast
the system runs).
So, fixed patch attached. Can you please test it once more and I will
submit it properly?
