H6: Desktop freezes/crashes

Description

Running desktop accelerated by Panfrost suffering from random freezes/crashes. This may be related to dvfs (https://armbian.atlassian.net/browse/AR-301#icft=AR-301). If this cannot be fixed for real until release a workaround can gain some stability to fix the gpu clock to a fixed value via devfreq.

If this workaround is implemented this line needs to be executed on any H6 board with HDMI on board before firing up DE:

cat /sys/devices/platform/soc/1800000.gpu/devfreq/1800000.gpu/max_freq > /sys/devices/platform/soc/1800000.gpu/devfreq/1800000.gpu/min_freq

This basically fixed the gpu clock to the highest possible value.
