Subject: [PATCH 4.16 035/110] cpufreq: armada-37xx: driver relies on cpufreq-dt

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Miquel Raynal <miquel.raynal@...tlin.com>

commit 0cf442c6bcf572e04f5690340d5b8e62afcee2ca upstream.

Armada-37xx driver registers a cpufreq-dt driver. Not having
CONFIG_CPUFREQ_DT selected leads to a silent abort during the probe.
Prevent that situation by having the former depending on the latter.
