MLK-13133-02 cpufreq: imx: Fix system hang when entring low bus mode on imx6ull
On i.MX6ULL, when the CPU freq is running at 198MHz or 396MHz, the system will
enter low bus mode if no device need high bus mode. The first time the system
entering low bus mode, CPU freq will be set to 24MHz, if cpufreq change the CPU
freq from 198MHz(396MHz) to 396MHz(198MHz), the CPU freq will be set to 198MHz or
396 MHz. At this time, if the CPU enter low power idle, system will hang.
