- clk_prepare_enable() can fail here and we must check its return value.
- oxnas_nand_probe() can fail here and we must disable clock.

We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

We only need to allocate sizeof(struct oxnas_nand_ctrl) which is 192
bytes and not sizeof(struct nand_chip) which is a much larger 3056
bytes.

Add NAND driver to support the Oxford Semiconductor OX820 NAND Controller.
This is a simple memory mapped NAND controller with single chip select and
software ECC.
