[Intel-gfx] [RFC-v4 00/21] Introduce Intel PXP component - Mesa single session

[Huang, Sean Z]

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

This patch series is to allow the kernel space to create and
manage a single hardware session (a.k.a default session or
arbitrary session). So Mesa can allocate the protected buffer,
which is encrypted with the leverage of the arbitrary hardware
session.

v2:
    - modification based on code reivew feedbacks received
    - passing pxp instead of i915 as funciton argument
    - remove dead code only for multi-session
    - move the pxp init call from i915_drv.c to intel_gt.c
    - reove the tautology naming

v3:
    - rebase to latest drm-tip

v4:
    - Append the split non-mesa patch sereis (commit #14 - #21) into this patch series
