The driver gpmi-nand should compile at least. This patch adds the missing gpmi-nand.h to fix the compile error below.

* @max_prop_delay_in_ns: Maximum propagation delay of GPMI signals to and

* should configure the hardware. This value most

* likely reflects the number of pins that are

* @partition_count: The number of elements in the partitions array.
