1ace9573dc x86/hevc_idct: replace old and unused idct functions 
Only 8-bit and 10-bit idct_dc() functions are included (adding others should be trivial).

idct8x8_dc
       SSE2   MMXEXT  C
cycles 22     26      57

idct16x16_dc
       AVX2   SSE2    C
cycles 27     32      249

idct32x32_dc
       AVX2   SSE2    C
cycles 62     126     1375
