	IPC messages transmitted to the device must be marked as allocated - status field must be set to 1. The VPU driver has IVPU_IPC_HDR_ALLOCATED incorrectly defined. Future VPU firmware versions will reject all IPC messages with invalid status and will not work with a VPU driver that is missing this fix.

2023-01-19	accel/ivpu: Add IPC driver and JSM messages	Jacek Lawrynowicz
	The IPC driver is used to send and receive messages to/from firmware running on the VPU. The only supported IPC message format is Job Submission Model (JSM) defined in vpu_jsm_api.h header.
