[PATCH v2 23/31] accel/ivpu: Refactor failure diagnostics during boot

[Jacek Lawrynowicz]

From: Karol Wachowski <karol.wachowski at intel.com>

Move diagnostic functions to common error handling within ivpu_boot()
function to ensure diagnostics are gathered even in cases where NPU
fails after successful boot (DCT and HWS init failures).
