Use reference clock count based loop instead of "udelay()" for sampling of counters to improve the accuracy of re-generated CPU frequency. "udelay()" internally calls "WFE" which stops the counters and results in bigger delta between the last set freq and the re-generated value from counters. The counter sampling window used in loop is the minimum number of reference clock cycles which is known to give a stable value of CPU frequency. The change also helps to reduce the sampling window from "500us" to "<50us". Suggested-by: Antti Miettinen <amiettinen@xxxxxxxxxx> Signed-off-by: Sumit Gupta <sumitg@xxxxxxxxxx> ---
