[lantiq] fixes NO_XIP on CFI0001 flash

Browse Source 
This patch disables the execute-in-place (XIP) support for flash on
lantiq. This has to be disabled since the bus which flash is connected
to does not support unaligned accesses. Resolves data bus errors on
Lantiq routers with Intel command set flash.
