Subject: [PATCH] drm/msm/adreno: Add support for SM7150 SoC machine

SM7150 has 5 power levels which correspond to 5 speed-bin values: 0,
128, 146, 167, 172. Speed-bin value is calulated as FMAX/4.8MHz round up
to zero decimal places.

The vendor's FW GMU is called a618_gmu.bin. And also a618 on SM7150 uses
a615 zapfw.

Add this as machine = "qcom,sm7150", because speed-bin values are
different from atoll (sc7180/sm7125).
