[PATCH for 4.9 23/59] clk: wm831x: fix usleep_range with bad range

From: Nicholas Mc Guire [ Upstream commit ed784c532a3d0959db488f40a96c5127f63d42dc ] The delay here is not in atomic context and does not seem critical with respect to precision, but usleep_range(min,max) with min==max results in giving the timer subsystem no room to optimize
