mtd: spinand: winbond: Declare the QE bit on W25NxxJW (2026-04-10 19:10:44 +0200)

----------------------------------------------------------------
The main changes happened in the SunXi driver in order to support new versions of the Allwinner NAND controller.

There are also some DT-binding improvements and cleanups.

Finally a couple of actual fixes (Realtek ECC and Winbond SPI NAND), aside with the usual load of misc changes.
