* commit 'fca3c3b61952aacc45e9ca54d86a762946c21942':
  hevc: Add AVX2 DC IDCT

Mostly noop as we already have that code.

In the ASM, code is merged with the exception of SECTION which is kept
uppercase for consistency with the rest of the codebase.

Still in the ASM, the prototype comment is fixed to honor the '_' added
from the original commit.

idct_dc_proto() is dropped as it's not used anymore here.

  hevc: Separate adding residual to prediction from IDCT

This commit should be a noop but isn't because of the following renames:

- transform_add  → add_residual
- transform_skip → dequant
- idct_4x4_luma  → transform_4x4_luma

The second stride is always the internal buffer one, MAX_PB_SIZE (times 2 to
get the value in bytes).
