    drm/i915/guc: Submit GuC workitems containing coalesced requests

    To create an upper bound on number of GuC workitems, we need to change
    the way that requests are being submitted. Rather than submitting each
    request as an individual workitem, we can do coalescing in a similar way
    we're handlig execlist submission ports. We also need to stop pretending
    that we're doing "lite-restore" in GuC submission (we would create a
    workitem each time we hit this condition). This allows us to completely
    remove the reservation, replacing it with a compile time check.

    v2: Also coalesce when replaying on reset (Daniele)
    v3: Consistent wq_resv - per-request (Daniele)
    v4: Squash removing wq_resv
    v5: Reflect i915_guc_submit argument changes in doc
    v6: Rebase on top of execlists reset/restart fix (Chris,Michał)
