[PATCH i-g-t 16/27] tools/intel_vbt_decode: Decode block 24 (SDVO LVDS PnP ID)

[Ville Syrjala]

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

Decode VBT block 24 (SDVO LVDS PnP ID). Just a set of four
PnP IDs (one for each SDVO panel type).

Example output from CST:
BDB block 24 (40 bytes, min 40 bytes) - SDVO LVDS PnP ID:
        0000: 18 28 00 36 7f 03 00 01  00 00 00 00 0c 36 7f 05
        0010: 00 02 00 00 00 00 0c 36  7f 01 90 03 00 00 00 00
        0020: 0c 36 7f 06 00 04 00 00  00 00 0c

        SDVO Panel 0
