arm64: dts: qcom: sm7225-fairphone-fp4: Enable SD card

Browse Source 
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.
