While investigating bug #101528, I've noticed another =
issue: FAN speed is too
high when display are off.

Display is off:
$ cat /sys/class/hwmon/hwmon6/fan1_input
1914

Display is on:
$ cat /sys/class/hwmon/hwmon6/fan1_input
941

In both cases sclk, mclk and pcie are in the same lowest state.

smu7_get_xclk() returns some crazy values when display is off.=

depends on some state that changes every boot.

So now after reboot I get a different FAN speed when display is off:
$ cat /sys/class/hwmon/hwmon6/fan1_input

When display is on, FAN speed is always consistent.
