spl: nand: rework SYS_NAND_U_BOOT_OFFS Kconfig option dependency
The SYS_NAND_U_BOOT_OFFS is quite generic, but the Kconfig entry is forced
to explicitly depend on platforms that are not already defining it in their
include/configs/<board>.h header.
Add the SYS_NAND_U_BOOT_LOCATIONS option, make the SYS_NAND_U_BOOT_OFFS
depends on it, remove the dependency on NAND_SUNXI and make it dependent
on SPL selection.
