The clock is in Hz while the value checked against is in kHz, so
actual frequencies will never be able to be below to max value.
Fix this by specifying the max-value in Hz too.

It seems the error message is incorrect as well and should be saying Hz
instead of KHz. (note also the lowercase z).
I think kHz is fine, we can find many siminary usage in drm:
drivers/gpu/drm/drm_vblank.c
656: drm_dbg_core(dev, "crtc %u: clock %d kHz framedur %d linedur %d\n",
