Rockchp's NFC(Nand Flash Controller) has four versions: V600, V622, V800 and
V900.This series patch can support all four versions.


Changes in v16:
- Fix some comments about 'ret' variable.

Changes in v15:

- Fix some comments.

Changes in v14:
- Add oob_read and oob_write hook api.
- Support timing config and ecc config for each chips.
- Fix some comments.

Changes in v13:
- The nfc->buffer will realloc while the page size of the second mtd
is large than the first one.
- Fix coding style.
- Fix some comments.

Changes in v12:
- Fix some warnings while make dt_binding_check
- Drop a allOf defined

Changes in v11:
- Fix compile error.

Changes in v10:

Changes in v9:
- The nfc->buffer will realloc while the page size of the second mtd
is large than the first one

- Remove struct rk_nfc_clk.
- Prepend some function with rk_nfc_.
- Replace function readl_poll_timeout_atomic with readl_relaxed_poll_timeout.
- Remove function rk_nfc_read_byte and rk_nfc_write_byte.
- Don't select the die if 'check_only == true' in function rk_nfc_exec_op.
- Modify function rk_nfc_write_page and rk_nfc_write_page_raw.

Changes in v8:
- Fix a error while make dt_binding_check

Changes in v7:
- Fix some wrong define
- Rebase to linux-next.
- Fix coding style.
- Reserved 4 bytes at the beginning of the oob area.
- Page raw read and write included ecc data.

Changes in v6:
- Fix some wrong define
- Modified the definition of compatible
- The mtd->name set by NAND label property.
- Add some comments.
- Fix compile error.

Changes in v5:
- Fix some wrong define.
- Add boot-medium define.
- Remove some compatible define.
- Add boot blocks support with different ECC for bootROM.
- Rename rockchip-nand.c to rockchip-nand-controller.c.
