platform: msm8916: Add Chip info for 8x3x and modify function declaration.

Add chip info for 8936 for setting baseband property for MSM8936 and to
determine platform as 8x3x. Also,the function to detect platform as 8x3x,
needs to be used in splash screen implementation,hence removing static to
make it accessible from a different file.
