[U-Boot] [PATCH 3/3 V2] ARM: mxs: Fix NAND FCB flashing

[Marek Vasut <marex@denx.de>]

Dear Marek Vasut,

> Fix the method of flashing FCB blocks into NAND. The new env
> writes all four FCB blocks and also does not scrub such a big
> part of the NAND. This fixed complains about busted NAND blocks

Uh, I think this might need to be update_nand_step instead of update_nand_stride 
here.
