msm: kgsl: Read speed bin information from device tree
Speed bin information is sometimes written to efuses to
specify a GPU frequency plan available on a platform. The
current code only supports reading the efuses for msm8996v3.
Hence specify it in the platform device tree node to
support multiple platforms.
