- 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.

- 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.
