Subject: [PATCH v2 3/5] arm64: defconfig: Enable devfreq support for i.MX8MQ

From: Guido Günther <agx@...xcpu.org>

This is needed to make DRAM frequency scaling via devfreq as used
on the Librem 5 and Librem 5 Devkit.

With the interconnect support enabled we now need imx devfreq on top
to make this work.
