arm: dts: berlin2q-marvell-dmp: add sdhci1 fully functionality
The sdhci1 on Marvell BG2Q DMP board is used as sdcard interface, we
have gpios for card detection, write-protect, vqmmc and vmmc.
This patch adds pinmux for this sdcard interface, then adds regulators
for vmmc and vqmmc, lastly adds cd-gpios, wp-gpios properties.
