arm64: dts: qcom: sm7225-fairphone-fp4: Enable SD card
Fairphone 4 uses sdhc_2 for the SD card, configure the pins for it and enable it. The regulators which are exclusively used for SDHCI have their maximum voltage decreased to what downstream sets on the consumer side, like on many other platforms and allowed to set the load.
