Subject: [PATCH AUTOSEL 5.15 71/82] memory: tegra20-emc: Add runtime dependency on devfreq governor module

From: Dmitry Osipenko <digetx@...il.com>

[ Upstream commit 14b43c20c283de36131da0cb44f3170b9ffa7630 ]

Tegra20 EMC driver uses simple devfreq governor. Add simple devfreq
governor to the list of the Tegra20 EMC driver module softdeps to allow
userspace initramfs tools like dracut to automatically pull the devfreq
module into ramfs image together with the EMC module.
