With this ioctl action, user space driver can reserve a specific
session slot/id assigned by PXP, as the first step of PXP session
establishment flow. The session info is stored in the session list
structure.

Implement the PXP ioctl action to allow user space driver to
terminate the hardware session and cleanup its software session
state. PXP sends the session termination command to GPU once
receves this ioctl action.

Teardown is triggered when the display topology changes and no
long meets the secure playback requirement, and hardware trashes
all the encryption keys for display. So as a result, PXP should
handle such case and terminate all the type0 sessions.

PXP should terminate the hardware session and cleanup the software

protection session, but doesn't close the session correctly due to
some cases like application crash.
