That was my first thought too...and it was wrong.
If of_clk_detect_critical does NOT detect a critical clock, it does not
touch flags at all.
And since it is a loop, what you get is after the first clock is marked
as CRITICAL, all the remaining clocks also get marked CRITICAL. In this
case, both spibsc0 and spibsc1 get marked critical. That's why I have to
reset it for each loop.
