Revert "overlay: delete storage_list.xml, it already defined in qcom-common"

This reverts commit b6f34ec60efebc979a1cda14e605d10b06b10af0.
overlay: storage: Import file from msm8x60-common repo

Must be present in your specific device tree, because it has dependencies with:
 - init.qcom.rc
 - fstab.qcom

We must test to add the option "android:emulated="false"" to complete the recommended configuration, and keep the file in line with fstab.qcom
