mtd: gpmi: remove unneccessary header 

The whole gpmi-nand driver has turned to pure devicetree supported.
So the linux/mtd/gpmi-nand.h is not neccessary now. Just remove it,
and move some macros to the gpmi-nand driver itself.

/**
* struct gpmi_nand_platform_data - GPMI NAND driver platform data.
*
* This structure communicates platform-specific information to the GPMI NAND
* driver that can't be expressed as resources.
*
* @platform_init: A pointer to a function the driver will call to
* initialize the platform (e.g., set up the pin mux).
* @min_prop_delay_in_ns: Minimum propagation delay of GPMI signals to and
* from the NAND Flash device, in nanoseconds.
* @max_prop_delay_in_ns: Maximum propagation delay of GPMI signals to and
* from the NAND Flash device, in nanoseconds.
* @max_chip_count: The maximum number of chips for which the driver
* should configure the hardware. This value most
* likely reflects the number of pins that are
* connected to a NAND Flash device. If this is
* greater than the SoC hardware can support, the
* driver will print a message and fail to initialize.
* @partitions: An optional pointer to an array of partition
* descriptions.
* @partition_count: The number of elements in the partitions array.
