Ok, will be done.

Well, that's not true for all the drivers, as we have tegra_nand.h and
atmel_nand_ecc.h, never used elsewhere apart from their corresponding
*.c files.

Especially if we'd have two drivers, one header will be needed.

But if that would ease your work, I'll merge sunxi_nand.h to
sunxi_nand.c and rename it as you suggest.
