[U-Boot] [PATCH 1/7 v11] powerpc: deleted unused symbol CONFIG_SPL_NAND_MINIMAL and enabled some functionality for common SPL

[ying.zhang at freescale.com]

From: Ying Zhang <b40530 at freescale.com>

1. The symbol CONFIG_SPL_NAND_MINIMAL is unused, so deleted it.
2. Some functions were unused in the minimal SPL, but it is useful
in the common SPL. So, enabled some functionality for common SPL.
