Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
In order to do that, we first need to update the platform_nand_ctrl
hooks to take a nand_chip object instead of an mtd_info.
We had temporary plat_nand_xxx() wrappers to the do the mtd -> chip
conversion, but those will be dropped when doing the patching nand_chip
hooks to take a nand_chip object.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all ecc->read_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all ecc->write_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all chip->read_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all chip->write_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->select_chip() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all chip->block_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->cmd_ctrl() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->dev_ready() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->cmdfunc() hook.

Let's make the raw NAND API consistent by patching all helpers and

remove the mtd_info object when both are passed.
Let's tackle the chip->waitfunc() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->erase() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->setup_data_interface() hook.

Let's tackle the nand_erase_nand() helper.
