[U-Boot] [PATCH 11/13] nand_spl_simple: store temp data at CONFIG_SPL_NAND_WORKSPACE

Currently nand_spl_simple puts it's temp data at 0x10000 offset in SDRAM
which is likely to contain already loaded data. I can't see any way to
determine some safe address automagically so make it up to board porter
to provide the safe-to-use address via CONFIG_SPL_NAND_WORKSPACE value.
