ARM: dts: msm: Move PMIC GPIO4 configuration on mdm9607

On MDM9X07 platforms where SD card is not present, the PMIC GPIO4 is
causing power leakage. PMIC GPIO4 is connected to external regulator which
is used by SD card. This GPIO configurations needs to be enabled only
for platform which has SD card.
So move this GPIO configuration from generic mtp/cdp DT files to SD card
specific DT file.
