EDAC/pnd2: Make read-only const array intlv static

Don't populate the const read-only array intlv on the stack at run time,
instead make it static. This also shrinks the object size:

  $ size pnd2_edac.o.*

     text    data     bss     dec     hex filename
    15632     264    1384   17280    4380 pnd2_edac.o.new
    15644     264    1384   17292    438c pnd2_edac.o.old
