MLK-12902: usdhc: Revert "MLK-11685-5 mmc: sdhci-esdhc-imx: no need busfreq for imx6qdl" This reverts commit 312979d1fcbd068d4ba0f461e974e7cbcc889548. When busfreq is at low bus mode, which is 24MHz, it means DDR/AHB/AXI will drop to 24MHz. At the same time, when in low busfreq mode, cpuidle can be in low power idle, DRAM will be put into self-refresh and DRAM IO will in low power mode to save power, so DMA will NOT work. So all peripherals that needs DMA, need to request bus freq to high setpoint when it is active. Signed-off-by: Haibo Chen <haibo.chen@nxp.com>
