[U-Boot] [PATCH] NAND: cmd_nand.c: fix invalid pointers to static relocated chip names

[Valeriy Glushkov]

When U-boot starting from NAND the pointers to chip names are set before relocation.
If the original memory block is overwritten after relocation that led to invalid
string data in the nand utility.
