[PATCH] sunxi-nand: fix the PIO instead of DMA implementation

[Markus Hoffrogge]

Hi Andre,

as this patch has been delegated to you,
I would like to mention, that this patch is superseding
 the patch https://patchwork.ozlabs.org/project/uboot/patch/20220330204543.3790-1-macroalpha82@gmail.com/
raised by Chris Morgan.

It should solve the issue in general and does not require to
revert to the former DMA implementation.

Kind regards
Markus
