ARM: dts: msm: Add missing QoS and devfreq table for sdhc on MSM8909

Add missing QoS and devfreq table for sdhc1 and sdhc2 device nodes.

Without the devfreq table, the clock scaling would happen with the
default parameters of 400KHz <-> 177MHz or 200MHz, which would impact
the performance.

The current qcom,cpu-dma-latency-us is not applicable on msm-3.18.
Hence, add the right QoS parameters so that driver can put the
correct vote as per the data load.
