8346440506 accel/ivpu: Add initial Wildcat Lake support
Add support for Wildcat Lake (WCL) CPUs.
Wildcat Lake contains NPU5 just like Panther Lake
hence the initial support is very simple and adds
only PCI IDs.

3477696345 accel/ivpu: Add support for hardware fault injection
Introduces the capability to simulate hardware faults for testing
purposes. The new `fail_hw` fault can be injected in
`ivpu_hw_reg_poll_fld()`, which is used in various parts of the driver
to wait for the hardware to reach a specific state. This allows to test
failures during NPU boot and shutdown, IPC message handling and more.

Fault injection can be enabled using debugfs or a module parameter.

72f7e16ecc accel/ivpu: Fix NOC firewall interrupt handling
The NOC firewall interrupt means that the HW prevented
unauthorized access to a protected resource, so there
is no need to trigger device reset in such case.

To facilitate security testing add firewall_irq_counter
debugfs file that tracks firewall interrupts.

525a3858aa accel/ivpu: Set 500 ns delay between power island TRICKLE and ENABLE
Follow HW documentation recommendation of 500 ns delay between setting
AON_PWR_ISLAND_TRICKLE_EN and AON_PWR_ISLAND_EN registers during power
island enabling. Previously this was only done correctly for VPU 4+.
VPU 3.7 had the delay added after power island disable where it is not
needed.

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.
