This provides a simpler, more direct alternative to the deprecated
aspeed,sirq-polarity-sense property for indicating the polarity of
the Aspeed VUART's SIRQ line.

Do you think we could make use of the approach I put forward here?

If you mean using a u32 property (say aspeed,sirq-polarity) with an 
explicit IRQ_TYPE_LEVEL_{LOW,HIGH} instead of a present/absent bool,
sure, I guess that seems like a somewhat clearer, more orthogonal 
arrangement.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:
./Documentation/devicetree/bindings/serial/8250.yaml:16:30: [warning] too few spaces after comma (commas)
./Documentation/devicetree/bindings/serial/8250.yaml:17:30: [warning] too few spaces after comma (commas)

dtschema/dtc warnings/errors:

See https://patchwork.ozlabs.org/patch/1460791

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
