Subject: [PATCH 04/12] 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:
warning: no previous prototype for function
