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.
