PXP is an i915 componment, that helps user space to establish the
hardware protected session and manage the status of each alive
software session, as well as the life cycle of each session.

This ioctl is to allow user space driver to create, set, and
destroy each session. It also provides the communication chanel to
TEE (Trusted Execution Environment) for the protected hardware
session creation.
