The spi-mtk-nor controller of mt8173, mt8186 and mt8192 have their
DT data. They don't use mt8173 as fallback.

Using the fallback of mt8186 to enables the controllers to support
mt8188.

Not all of spi-mtk-nor controller need interrupt property, so we
don't mark interrupt as required.

[1/1] spi: dt-bindings: mediatek,spi-mtk-nor: Update bindings for nor flash
      commit: 82cef0af296d3de95c8c7005f640449d45bcef62

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
