Enable the NAND and UBI support in the configuration header so that we can (finally) use it.

Can we make this configurable through Kconfig?
Is there a need for that?
Yes, I think so, since each board has a different kind of NAND (with possibly different eraseblock size) and I'm not sure this is always acceptable to lose 8MiB of storage for the SPL images (especially for small SLC NANDs).
AFAIK, everyone in U-Boot defines it there (and converting everyone to Kconfig for all the CONFIG_SYS_NAND options is going to be painful).
It already exists: enable the SYS_NAND_U_BOOT_LOCATIONS Kconfig option, and you should see the SYS_NAND_U_BOOT_OFFS and SYS_NAND_U_BOOT_OFFS_REDUND ones.
Thanks! Maxime
