      ARM: dts: Disable smc91x on n900 until bootloader dependency is removed · b16ccfe0

      I added smc91x support but turns out we currently do not set the
      smc91x timings in gpmc.c but rely on the bootloader timings. This
      produces the following error unless the smc91x GPMC timings are
      initialized by the bootloader:

      Let's fix the issue by disabling the smc91x module for now until we
      have sorted out the issues in gpmc.c.
