mtd: rawnand: fsmc: Fix use of SM ORDER
The introduction of the generic ECC engine API lead to a number of changes in various drivers which broke some of them. Here is a typical example: I expected the SM_ORDER option to be handled by the Hamming ECC engine internals. Problem: the fsmc driver does not instantiate (yet) a real ECC engine object so we had to use a 'bare' ECC helper instead of the shiny rawnand functions. However, when not intializing this engine properly and using the bare helpers, we do not get the SM ORDER feature handled automatically. It looks like this was lost in the process so let's ensure we use the right SM ORDER now.
