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.
