To enable runtime PM for an SD cardreader (device number 0:0:0:0), do:

when actually a medium changed but also simply when resuming from suspend.
(probably because the device can't know what happens during suspend and
want to say "medium could have changed").

To enable runtime PM for an SD cardreader (here, device number 0:0:0:0),
do the following:
echo 0 > /sys/module/block/parameters/events_dfl_poll_msecs
echo 1000 > /sys/bus/scsi/devices/0:0:0:0/power/autosuspend_delay_ms
echo auto > /sys/bus/scsi/devices/0:0:0:0/power/control
I'd appreciate any feedback.

Note that on the Librem 5 devkit that uses a different revision of the
imx8mq SoC, the added flag does *not* break said clock reparenting so
there might be subtle differences here.

This is a workaround for a hardware bug in the r3 revision that basically would
stop the system due to traffic on the i2c1 bus. A cpu voltage change would
trigger such traffic and that's what is avoided in order to work around it.
