Refactor to msm8660-common 

To complete the refactoring, we need:
 - Add this repository: https://github.com/mifl/android_device_pantech_msm8660-common.
 - Include this modification: https://github.com/PantechDevTeam/android_device_pantech_qcom-common/pull/3

The reason for these changes is to adapt the structure of the codeaurora repository, that also begin to use Cyanogenmod for Samsung devices.

There is some commented lines, which are part of the necessary changes to the version "cm-10.1" (# TARGET_QCOM_DISPLAY_VARIANT: = caf)
