Subject: [PATCH 5.10 014/299] arm64: dts: marvell: armada-37xx: add syscon compatible to NB clk node

From: Marek Behún <kabel@...nel.org>

commit 1d88358a89dbac9c7d4559548b9a44840456e6fb upstream.

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.
