[PATCH V2 00/11] Enable FW assisted shadowing for GFX11

[Alex Deucher]

This patch set allows for FW assisted shadowing on supported
platforms.  A new enough CP FW is required.  This feature is
required for mid command buffer preemption and proper SR-IOV
support.  This also simplifies the UMDs by allowing persistent
hardware state when the command submission executes.  UMDs
that use this will have their state retained across command
submissions.

The mesa MR to implement the user mode side of this is:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/21986

v2: Integrate feedback from V1.  UMDs now need to specify init_shadow
    on first use.
