ENGR00221902 [MX6]Fix udelay inaccurate issue during suspend/resume

When system enter suspend, we increase CPUFreq to the highest point
without update the global loops_per_jiffy, it will lead to udelay
inaccurate during the last phase of suspend/resume.

WB counter and RBC counter need at least two 32K cycles to finish,
here we add 80us for safe.
