高通平台如何确定使用 ISP version
1. vendor下面的 ISP version

搜索8953，可以发现使用如下
else ifeq ($(call is-board-platform-in-list,msm8937 msm8953),true)
LOCAL_C_INCLUDES += $(LOCAL_MMCAMERA_PATH)/media-controller/modules/isp2/module/isp42
即使用的是ISP42
2. kernel的 ISP version
kernel/msm-3.18/arch/arm64/boot/dts/qcom/msm8953-camera.dtsi: compatible = "qcom,vfe40"; 综合可以得到vendor下面的是isp42 ，kernel下面的是isp40
