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.

testing this set of patch on IFC6540, i noticed that not all
partitions from the eMMC are detected. booting [1] which is basically
3.17-rc7 with a few additional patches, i can see the following
relevant mmc traces:

This has bitten me more times than I care to admit, but have you checked
that you've set CONFIG_MMC_BLOCK_MINORS higher than 16?  Perhaps we
should be doing that in qcom_defconfig if we aren't already.
