dt-bindings: samsung: exynos-pmu: Narrow allowed reboot modes
syscon-reboot-mode schema allows arbitrary "mode-.* properties but only
a subset actually makes sense and is valid. Provide negative look-ahead
pattern to disallow any modes not supported by the device, which
tightens the binding.
Most of Android-based Exynos devices share the bootloader or its parts,
thus reboot modes are most likely the same, however only a few upstream
DTS define them, so add restrictions only for these.
Google GS101 has on the other hand quite different bootloader with many
known reboot modes.
