MLK-12203-2 ARM: imx: adjust loop number to delay ~20us for i.MX7D low power idle ARM does NOT execute one instruction every cycle, the bus bandwidth, cache status etc. would impacts the instruction execution time, so we can NOT just calculate the delay time by ARM frequency, this patch adjusts loop number to get a ~20us delay, measured via GPIO pin.
