lantiq: disable buffered writes on Intel command set flash Some Lantiq SoCs are not able to use buffered writes properly with Intel command set flash due to the way NOR addresses on EBU are manipulated. This patch disables buffered writes on those devices. The only device affected at the moment is ARV4510PW, others use AMD/Fujitsu command set.
