Pull request for u-boot-nand-20231013

The first 5 patches are from Mikhail Kshevetskiy, aligning the mtd spinand
core with kernel version 5.15.43, fixing a bug on Winbond, and adding
support for Winbond W25NO2KV.

The other 2 patches are from Patrick Delaunay and they fix a bug and mark
bad the MTD block on erase error.
