The usage count of struct dev_pm_info is an implementation detail that
is only available if CONFIG_PM is enabled, so printing it in a debug message
causes a build failure in configurations without PM:
In file included from include/linux/device.h:15,

253 | ivpu_dbg(vdev, RPM, "rpm_get_if_active count %d\n",
| ^~~~~~~~
The print message does not seem essential, so the easiest workaround is
to just remove it.
Fixes: c39dc15191c4 ("accel/ivpu: Read clock rate only if device is up")
