[PATCH mvebu v3 01/10] arm64: dts: marvell: armada-37xx: add syscon compatible to NB clk node

[Pali Rohár]

From: Marek Behún <kabel@xxxxxxxxxx>

Add "syscon" compatible to the North Bridge clocks node to allow the
cpufreq driver to access these registers via syscon API.

This is needed for a fix of cpufreq driver.
