[PATCH v2 3/3] ARM: dts: qcom: Add SDHC nodes for APQ8084 platform

Enable support for the two SD host controllers on the APQ8084 platform
by adding the required nodes to the DT files.
On the IFC6540 board, the first controller is connected to the onboard
eMMC and the second is connected to a micro-SD card slot.
