regulator: max8660: fix assignment of pdata to data that becomes dead

pdata is assigned to &pdata_of, however, pdata_of becomes dead (when it
goes out of scope) so pdata effectively becomes a dead pointer to the
out of scope object.  This is detected by static analysis:

[drivers/regulator/max8660.c:411]: (error) Dead pointer usage.
  Pointer 'pdata' is dead if it has been assigned '&pdata_of' at line 404.

Move declaration of pdata_of so it is always in scope.
