intel/genxml: Collapse leading underscores on prefixed value defines

Browse source 
We prefix names with an underscore to make them "safe" C identifiers
when necessary.  For example, a value of "32x32" would become "_32x32".

However, when specifying something like

   <field ... prefix="BLOCK_SIZE">
     <value name="32x32" value="0"/>
   </field>

we already have a prefix that makes the field name safe.  We'd rather
generate a name with a single underscore, i.e.

    #define BLOCK_SIZE_32x32 0

rather than

    #define BLOCK_SIZE__32x32 0

This also fixes up affected defines in crocus.
