[PATCH 33/35] drm/i915/bios: Define VBT block 55 (Compression Parameters)

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

Define the contents of the obsolete VBT block 55 (Compression
Parameters).

This was some early attempt at defining the compression
parameters. However the spec says:
"This block is obsolete and should not be consumed for any
 compression programming."

Block 56 is the replacement that should actually be used.

So let's just name the obsolete old block but not even
bother defining the contents.
