My preference here is that we maintain two separate DTS for Wedge400:

- aspeed-bmc-facebook-wedge400.dts
- aspeed-bmc-facebook-wedge400-data64.dts

We do so such that we implement aspeed-bmc-facebook-wedge400.dts like:

   > cat aspeed-bmc-facebook-wedge400.dts
   #include "aspeed-bmc-facebook-wedge400-data64.dts"
   
   &fmc_flash0 {
   /delete-node/partitions;
   #include "facebook-bmc-flash-layout-128.dtsi"
   };

aspeed-bmc-facebook-wedge400-data64.dts includes facebook-bmc-flash-
layout-128-data64.dtsi as usual.
