Hi!
The series adds support for PECI on Nuvoton-based BMC boards.
It is based on patches that were sent by Tomer Maimon from
Nuvoton [1].
Similar to Aspeed driver, unused (as in, default values were used in
all of the available DTS files) vendor-specific properties were
removed.
If there is a use-case for such properties, they can be added in
a separate series.
Thank you Tomer for testing this series on Nuvoton hardware [2].
Please note that PECI Nuvoton was previously submitted as part of PECI
subsystem series [3] that was never merged upstream.
It was never included in the current in-tree PECI subsystem [4].

Changes v1 -> v2:
* Renamed binding filename to match compatible (Krzysztof)
* Removed period from the end of copyright (Paul)
Thanks
