drm/amd/display: Remove the unused function link_timing_bandwidth_kbps()

Browse Source 
The function link_timing_bandwidth_kbps is defined in the
link_validation.c file, but not called elsewhere, so remove this unused
function.

drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_validation.c:258:10: warning: no previous prototype for ‘link_timing_bandwidth_kbps’.
