PXP tag, which is a 32-bit bitwise value indicating the current
session info, including protection type, session id, and whether
the session is enabled.

Same old gem_create but with now with extensions support. This is needed
to support various upcoming usecases. For now we use the extensions
mechanism to support PAVP.

Implement the ioctl action to allow userspace driver sends TEE
commands via PXP ioctl, instead of TEE iotcl. So we can
centralize those protection operations at PXP.

With this ioctl action, userspace driver can reserve one or
multiple session slot/id assigned by kernel PXP, as the first
step of PXP session establishment flow. The session info is
stored in the session list structure.

In the previous commits, we have implemented the PXP ioctl
functions. Now we enable those handlers and expose them as PXP
ioctl, so allow the userspace driver can establish, set, or

Implement the intel_pxp_gem_object_status() to allow i915 display
querying the current PXP session state. In the design, display
should not perform protection flip on the protected buffers if
there is no PXP session alive.
