feat(msm8916): add port for MSM8939

The Qualcomm Snapdragon 615 (MSM8939) SoC is very similar to the
existing MSM8916, except for:

  - Two clusters with ARM Cortex-A53 cores
  - CCI-400

Make the existing MSM8916 platform port usable for MSM8939 as well by
adding some minimal if statements where necessary plus the platform
make files for msm8939.
