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:

[    1.162587] mmc0: BKOPS_EN bit is not set
[    1.315357] mmc0: new HS200 MMC card at address 0001

[    1.333652] mmcblk0boot1: mmc0:0001 SEM16G partition 2 4.00 MiB

[    1.365902]  mmcblk0boot1: p1
[    1.367833]  mmcblk0boot0: unknown partition table

on the same board, booting the board vendor kernel (which is based on
QCOM 3.10 tree), i can see much more partitions:

[    7.662379] mmc0: BKOPS_EN bit = 0
[    7.673036] mmc0: new HS200 MMC card at address 0001
[    7.673784] mmcblk0: mmc0:0001 SEM16G 14.6 GiB
[    7.674311] mmcblk0rpmb: mmc0:0001 SEM16G partition 3 4.00 MiB
[    7.677967]  mmcblk0: p1 p2 p3 p4 p5 p6 p7 p8 p9 p10 p11 p12 p13
p14 p15 p16 p17 p18 p19 p20 p21 p22 p23 p24\
 p25

the complete dmesg log for can be found in our board lab, at [2]
