[PATCH v3 0/4] aspeed-vuart: generalized DT properties

This series generalizes the aspeed-vuart driver's device tree
properties to cover all the attributes it currently exposes via sysfs.
The aspeed,sirq-polarity-sense property was a bit of a design mistake
in that it ties Aspeed VUART SIRQ polarity to SCU register bits that
aren't really inherently related to it; the first patch in this series
deprecates it (though we hope to eventually remove it).
The rest of the series adds two new properties, aspeed,lpc-address and
aspeed,sirq. The latter allows describing the SIRQ polarity (along
with the interrupt number) directly, providing a simpler replacement
for aspeed,sirq-polarity-sense.
Changes since v2 [0]:
- expanded to also handle sirq number and lpc address in addition to
sirq polarity
- added default settings if DT properties not specified
- refactored existing sysfs code slightly, adding range checks
- cleaned up 'make dt_binding_check' warnings
Changes since v1 [1]:
- deprecate and retain aspeed,sirq-polarity-sense instead of removing it
- drop e3c246d4i dts addition from this series
