Add sandbox DM unit tests for the PHY common properties library and the corresponding device tree test nodes to arch/sandbox/dts/test.dts. Also enable CONFIG_PHY_COMMON_PROPS in configs/sandbox_defconfig so the tests are built and run in the sandbox environment. The test file covers rx/tx polarity lookups for all relevant cases: - missing property (defaults to PHY_POL_NORMAL) - single value without names array (applies to all modes) - count mismatch between values and names arrays (-EINVAL) - name found by exact match - name not found with no "default" fallback (-EINVAL) - name not found with a "default" entry (uses fallback value) - unsupported polarity value (-EOPNOTSUPP) Ported from Linux KUnit test: linux/drivers/phy/phy-common-props-test.c Signed-off-by: Lucien.Jheng <lucienzx159@gmail.com>
