Add a new PHY_COMMON_PROPS library that provides helper functions for
PHY drivers to read standardized polarity properties from the device

- phy_get_rx_polarity() / phy_get_tx_polarity()
- phy_get_manual_rx_polarity() / phy_get_manual_tx_polarity()
The dt-bindings/phy/phy.h header with PHY_POL_NORMAL, PHY_POL_INVERT,
and PHY_POL_AUTO constants is provided via dts/upstream/include, which
is already in the build include path.

Thanks for doing this. Do you think you can also port the KUnit tests to
U-Boot's own "ut" test framework? Should be testable with the sandbox.
export KBUILD_OUTPUT=output-sandbox
make sandbox_defconfig NO_SDL=1
make -j 8 NO_SDL=1
$KBUILD_OUTPUT/u-boot -d $KBUILD_OUTPUT/arch/sandbox/dts/test.dtb
ut phy # or phy_common_props for the new code
I haven't used KUnit before, but I'll try to port it to U-Boot.
Let me look into the commands you provided and figure out how to port it.
Thanks
