ppc4xx: Fix ndfc HW ECC byte order

Browse source 
The current ndfc HW ECC implementation swaps the first two ECC bytes.
But the 4xx NDFC already uses the SMC (Smart Media Card) ECC ordering,
so this swapping in the HW ECC driver is bogus. This patch fixes this
problem and now really uses the SMC ECC byte order.

Thanks to Sean MacLennan for pointing this out.
