CEA-861-F introduces extended tag codes for EDID extension blocks, which indicates the actual type of the data block. The code for using exteded tag is 0x7, whereas in the existing code, the corresponding macro is named as "VIDEO_CAPABILITY_BLOCK"
This patch renames the macro and usages from "VIDEO_CAPABILITY_BLOCK" to "CEA_EXTENDED_TAG"
