Main thing that this patchset adds is support for waiting for command
completion when there is no wired ready/busy pin. This is implemented
by using Meson specific command which operates without wired pin, but
supports interrupt driven waiting (default way for waiting without
hardware pin is 'nand_soft_waitrdy()' which uses software loop instead
of interrupt). To select which mode to use during driver initialization,
common NAND controller property is used - 'nand-rb'. It is described in
'nand-controller.yaml'. But for Meson, its description was missed in
'amlogic,meson-nand.yaml', so this patchset also adds support for it.

Patch for bindings was tested with dt_binding_check and dtbs_check.

Changelog:
* Two separate patches:
  For bindings: https://lore.kernel.org/linux-mtd/20230606193507.35024-1-AVKrasnov@sberdevices.ru/ (local)
  For driver: https://lore.kernel.org/linux-mtd/20230607073015.1280085-1-AVKrasnov@sberdevices.ru/ (local)
  Now fixed/updated and combined to this patchset with v1 version.

* In binding patch:
  * Invalid type of 'nand-rb' is fixed, it was 'bool', now it is 'uint32 array' as required. Also
    new declaration of 'nand-rb' contains several restrictions like number of elements and min/max
    value of elements.
  * Location of 'nand-rb' is moved from the controller object to the chip object as required.

Version your patchsets. This is v2, not v1.

Ack, next will be v3

Thanks, Arseniy

Best regards,
Krzysztof
