[PATCH i-g-t 17/27] tools/intel_vbt_decode: Decode block 25 (SDVO LVDS PPS)

[Ville Syrjala]

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

Decode VBT block 25 (SDVO LVDS PPS). Four sets (one for each SDVO
panel type) of power sequencing delays.

Example output from CST:
BDB block 25 (40 bytes, min 40 bytes) - SDVO LVDS PPS:
        0000: 19 28 00 19 00 fa 00 fa  00 19 00 90 01 20 00 20
        0010: 00 20 00 20 00 c8 00 40  00 40 00 40 00 40 00 2c
        0020: 01 40 00 40 00 40 00 40  00 2c 01

        SDVO Panel 0
                T0: 25 ms
                T1: 250 ms
                T2: 250 ms
                T3: 25 ms
                T4: 400 ms
        ...
        SDVO Panel 3 (*)
                T0: 64 ms
                T1: 64 ms
                T2: 64 ms
                T3: 64 ms
                T4: 300 ms
