Some mach-specific drivers that don't require their own node in the device tree
(for example drivers/soc/*, cpufreq, cpuidle etc.) want to match on the device
tree root compatible property instead. Instead of open-coding (and forgetting
to call of_node_put on the root node) everywhere, add a helper to the OF core.

Tuomas Tynkkynen (3):
  of: Add of_match_machine helper
  soc/tegra: Use of_match_machine in soc_is_tegra()
  cpuidle: big.LITTLE: Use of_match_machine
