Add pxp mode devstate to debugfs to monitor pxp state machine progress. This is useful to debug issues in scenarios in which the pxp state needs to be re-initialized, like during power transitions such as suspend/resume. With this debugfs the state could be monitored to ensure that pxp is in the ready state.

Sending OS version for support of TPM2_ChangeEPS() is required only for SPT FW (HMB version 2.0) and newer. On older platforms the command should be just ignored by the firmware but some older platforms misbehave so it's safer to send the command only if required.

mei: support for dynamic clients
HBM version 2.0 and above allows ME clients in the system to register/unregister after the system is fully initialized. Clients may be added or removed after enum_resp message was received
1. To preserve backward compatibility the driver can opt-in to receive client add messages by setting allow_add field in enum_req
2. A new client is added upon reception of MEI_HBM_ADD_CLIENT_REQ_CMD
3. A client is removed in a lazy manner when connection request respond with MEI_HBMS_CLIENT_NOT_FOUND status
