[PATCH] drm/amd/display: Disable -Wenum-float-conversion for dml2_dpmm_dcn4.c

[Nathan Chancellor <nathan@kernel.org>]

Commit be4e3509314a ("drm/amd/display: DML21 Reintegration For Various
Fixes") blew away commit fdedd77b0eb3 ("drm/amd/display: Reapply
2fde4fdddc1f"), which itself was a reapplication for the same reason,
which results in that compiler warning returning:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_dpmm/dml2_dpmm_dcn4.c:215:58: error: arithmetic between enumeration type 'enum dentist_divider_range' and floating-point type 'double' [-Werror,-Wenum-float-conversion]
    215 |         divider = (unsigned int)(DFS_DIVIDER_RANGE_SCALE_FACTOR * (vco_freq_khz / clock_khz));
        |                                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~

Just disable the warning for the whole file via Makefile to avoid having
to reapply the same fix every time the code syncs from wherever it is
actually maintained.

If you would prefer reapplying the local fix, feel free to do so, but I
would like for it to be in the upstream source so it does not have to
keep being applied.
