So I come up with the following idea:
1. With my current path, replace all reference to
   CONFIG_SYS_NAND_U_BOOT_OFFS with spl_nand_get_uboot_raw_page()
2. Add a new weak function, spl_nand_get_uboot_raw_page_redund(), to
   wrap the CONFIG_SYS_NAND_U_BOOT_OFFS_REDUND macro, and do the same
   modification as spl_nand_get_uboot_raw_page() do.

I'll send new patch later
