From: Ville Syrjälä <ville.syrj...@linux.intel.com>
New stuff has been added to the end of the child device block at various
times, so using a hardcoded size for the block is a bad idea.
Fortunately the size of the block is listed in the VBT just before the
blocks themselves, so grab it from there.
