Merge tag 'nand/for-6.19' into mtd/next

Raw NAND changes:

* The major change in this MR will be the support for the Allwinner H616
  NAND controller, which lead to numerous changes and cleanups in the
  driver.

* Another notable change on this driver is the use of
  field_get()/field_prep(), but since the global support for this
  helpers is going to be merged in the same release as we start using
  these helpers, it implies undefining them in the first place to avoid
  warnings. Depending on the merging order (Yuri's bitmap branch or
  mtd/next), a temporary warning may arise.

* Marvell drivers layout handling changes have also landed, they fix
  previous definitions and abuses that have been made previously, which
  implied to relax the ECC parameters validation in the core a bit.

* The Cadence NAND controller driver gets NV-DDR interface support.

SPI NAND changes:

* Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.

Aside from these main changes, there is the usual load of fixes and API
updates.
