tools/intel_vbt_decode: Decode block 26 (TV Options)
Decode VBT block 26 (TV Options). Nothing particularly interesting
in there for us.
Example output from CST:
BDB block 26 (2 bytes, min 2 bytes) - TV options:
0000: 1a 02 00 00 00
D connector support: no
Add modes to avoid overscan issue: no
Undescan/Overscan for HDTV via DVI: Neither
Undescan/Overscan for HDTV via component: Neither
