Add three debugfs hooks: * status: Check if we have a connection with the CSME firwmare. This hook is a read only. * req_ownership: Send a SAP command to request ownership. This flow should be triggered by iwlwifi (from user space through vendor commands really), but being able to trigger an ownership request from debugfs allows us to request ownership without connecting afterwards. This is an "error" flow that the CSME firmware is designed to handle this way: + Grant ownership since the host asked for it + Wait 3 seconds to let the host connect + If the host didn't connect, take the device back (forcefully). + Don't grant any new ownership request in the following 30 seconds. This debugfs hook allows us to test this flow. * send_start_message: Restart the communication with the CSME firmware from the very beginning. At the very beginning (upon iwlwifi start), iwlmei send a special message: SAP_ME_MSG_START. This hook allows to send it again and this will retrigger the whole flow. It is important to test this restart in the middle of normal operation since it can happen (in case the CSME firmware decided to reset for example).
