The change to edid_checksum is needed because the DisplayID section has another
checksum inside for the actually used part of its 128-byte extension block. The
checksum in this case uses the same algorithm, but for a shorter block. Thus I
added a parameter to specify the size of the block.

Adding these should be splitted to a separate patch.
