amdgpu/dc: Fix enum mismatch in calls to program_color_matrix()

The driver passes GRAPHICS_CSC_ADJUST_TYPE_SW of type enum
graphics_csc_adjust_type to program_color_matrix(), however the function
expects a parameter of type enum grph_color_adjust_option. Supposedly
the intention was to pass GRPH_COLOR_MATRIX_SW, which has the same value
as GRAPHICS_CSC_ADJUST_TYPE_SW, so the mismatch didn't cause any trouble.

Pass GRPH_COLOR_MATRIX_SW to program_color_matrix() instead of
GRAPHICS_CSC_ADJUST_TYPE_SW, this also fixes the following warning when
building the kernel with clang:

drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_transform.c:1129:24:
  error: implicit conversion from enumeration type
  'enum graphics_csc_adjust_type' to different enumeration type
  'enum grph_color_adjust_option' [-Werror,-Wenum-conversion]
    xfm_dce, tbl_entry, GRAPHICS_CSC_ADJUST_TYPE_SW);
