[PATCH v4 0/2] mtd: spi-nand: Add support for randomizer feature

[Cheng Ming Lin <linchengming884@gmail.com>]

From: Cheng Ming Lin <chengminglin@mxic.com.tw>

This patch series introduces randomizer support for SPI NAND devices.

Patch 1 adds the hook and initialization logic to the core framework.
Patch 2 implements the randomizer setting specifically for Macronix
chips (MX35LF/UF series) and allows control via device tree.

v4:
* Fix a build error in spinand_randomizer_init() where a value was
  returned from a void function. (Reported by kernel test robot)
* Update the return type to int.

v3:
* Revert the device tree property to the vendor-specific
  "mxic,randomizer-enable" to strictly follow vendor-specific bindings.

* Update the 'set_randomizer' callback signature to accept a boolean
  'enable' argument, allowing the feature to be explicitly enabled or
  disabled.

* Switch the implementation to use the standard SET_FEATURE command
  to modify the Configuration Register (0x10), replacing the previous
  special program command method.

v2:
* Create a global NAND DT property
