drm/i915/bios: Define VBT block 25 (SDVO LVDS PPS) contents

Define the contents of VBT block 25 (SDVO LVDS PPS).

Not 100% sure about the order of the fields as this is not
documented in the VBT spec anymore, but this order matches
what is included as part of the power sequencing SDVO commands
(struct sdvo_panel_power_sequencing). Also the real world
VBT data I have looks OK with this definition.
