Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c: In function
get_pbn_from_timing:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:2364:11: warning:
variable bpc set but not used [-Wunused-but-set-variable]
It is not used since commit e49f69363adf ("drm/amd/display: use
proper formula to calculate bandwidth from timing"), this also
remove get_color_depth(), which is only used here.

v2: also remove unused get_color_depth()
