description:
ST40_PMB_DA_BITS - all values for the non-continuous size field.

Size field has two reserved bits in the middle.  Don't depend on them
being zero, they can be defined in future versions.  Provide exhaustive
list with all possibile "filler" bits in the middle so that we
correctly report the size field value regardless of the unrelated bits.
