accel/ivpu: Return max freq for DRM_IVPU_PARAM_CORE_CLOCK_RATE

Browse source

DRM_IVPU_PARAM_CORE_CLOCK_RATE returns current NPU frequency which
could be 0 if device was sleeping. This value isn't really useful to
the user space, so return max freq instead which can be used to estimate
NPU performance.

Fixes: c39dc15191 ("accel/ivpu: Read clock rate only if device is up")
