a19bffb10c accel/ivpu: Implement DCT handling 
When host system is under heavy load and the NPU is already running
on the lowest frequency, PUNIT may request Duty Cycle Throttling (DCT).
This will further reduce NPU power usage.

PUNIT requests DCT mode using Survabilty IRQ and mailbox register.
The driver then issues a JSM message to the FW that enables
the DCT mode. If the NPU resets while in DCT mode, the driver request
DCT mode during FW boot.

Also add debugfs "dct" file that allows to set arbitrary DCT percentage,
which is used by driver tests.

8a27ad81f7 accel/ivpu: Split IP and buttress code 
The NPU device consists of two parts: NPU buttress and NPU IP.
Buttress is a platform specific part that integrates the NPU IP with
the CPU.
NPU IP is the platform agnostic part that does the inference.

This separation enables support for multiple platforms using
a single NPU IP, so for example NPU IP 37XX could be integrated into
MTL and LNL platforms.

The driver tracks the time spent by NPU executing jobs
and shares it through sysfs `npu_busy_time_us` file.
It can be then used by user space applications to monitor device

NPU is considered 'busy' starting with a first job submitted
to firmware and ending when there is no more jobs pending/executing.

This deadlock was reported by lockdep and observed in internal tests.

34d03f2a17 accel/ivpu: Initialize context with SSID = 1 
Context with SSID = 1 is reserved and accesses on that context happen
only when context is uninitialized on the VPU side. Such access triggers
MMU fault (0xa) "Invalid CD Fetch", which doesn't contain any useful
information besides context ID.

This commit will change that state, now (0x10) "Translation fault" will
be triggered and accessed address will shown in the log.
