[U-Boot] Canyonlands does not build anymore

[Eibach, Dirk]

The following commit modified include/asm-ppc/config.h so that
config_canyonlands has CONFIG_FSL_DMA active (because of
CONFIG_DDR_ECC), which is probably not intended. I'm not sure how to fix
this properly, maybe some Freescale guru could comment.

Cheers
Dirk
