[PATCH v2] accel/ivpu: Improve IVPU_TEST_MODE_FW_TEST handling

[Andrzej Kacprowski <andrzej.kacprowski@linux.intel.com>]

In IVPU_TEST_MODE_FW_TEST mode the driver triggers a firmware boot but
does not wait for boot completion. Because it never waits for the boot
to finish, it cannot send a message and expect a response from the
firmware.

Exit ivpu_boot() early in this mode, bypassing ivpu_hw_sched_init() and
the rest of the post-boot initialization. ivpu_hw_sched_init() was
sending a message that timed out and failed the boot sequence.
