drm/amd/display: Remove unused dml32_CalculatedoublePipeDPPCLKAndSCLThroughput function 



Remove dml32_CalculatedoublePipeDPPCLKAndSCLThroughput function, which is not used in
the codebase.

This was pointed by clang with the following warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c:393:6:
