accel/ivpu: Pass D0i3 residency time to the VPU firmware

Browse source

The firmware needs to know the time spent in D0i3/D3 to
calculate telemetry data. The D0i3/D3 residency time is
calculated by the driver and passed to the firmware
in the boot parameters.

The driver also passes VPU perf counter value captured
right before entering D0i3 - this allows the VPU firmware
to generate monotonic timestamps for the logs.
