ARM: dts: msm: Set SD card property for 8909 SKUA

There is no card-detect gpio in this hardware, but SD card can
still be removed without power-off the device.

1. set cd-gpio as pull down when suspend and resume to avoid
trigger QDSD debugger rescan process.
2. delete property cd-gpios and status_irq as SD card hot swap
is not support.
3. set qcom,nonhotplug to ensure device would not crash when
SD card is removed without power-off the device.
