Change-Id: I499e4c258042da9f2c20d9b95177ef97c461bdfc
Inherit from msm8960-common

* msm8960-common then inherits from qcom-common.
* This doesn't change anything currently, just adds one more
  common tree in between - however, later on, we can start moving
  things to this new tree as needed, from both nicki
  and qcom-common
