Copy the API version array from the firmware image header into
struct ivpu_fw_info while the header is being parsed, and use the

accessed during image parsing, which is a step towards releasing the
firmware image once it has been loaded.
Since the API version is now available in vdev->fw before the
compatibility checks run, drop the redundant fw_hdr parameter from
IVPU_FW_CHECK_API_COMPAT(), IVPU_FW_CHECK_API_VER_LT() and the helpers
behind them, as well as from ivpu_fw_sched_mode_select().
Also make DRM_IVPU_PARAM_FW_API_VERSION read the cached copy instead of
dereferencing the firmware image directly.
No functional change.
