wifi: iwlwifi: mei: add support for SAP version 4

Browse source

SAP version 4 uses larger Host to MEI notification queue.
Since it is unknown which SAP version is used by the CSME firmware
when the driver loads, try version 4 first. In case the CSME firmware
uses version 3, the memory allocation will fail. In this case the
driver will try again to allocate the memory for version 3.
