[PATCH i-g-t 18/27] tools/intel_vbt_decode: Decode block 26 (TV Options)

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

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
