nand: add containing structure for NAND platform data

In order to make it more convenient to pass platform-specific NAND stuff to a generic driver which is hopefully to come out next, I've introduced a container structure for chip-specific and controller-specific data. I'd expect that use cases in platform code will be like

struct platform_nand_data nand_data = {
	...
};

struct platform_device nand_device = {
	...
	.dev = {
		.platform_data = &nand_data,
		...
	},
};

So, please find the patch below.
