drm/i915/guc: Update intel_gt_wait_for_idle to work with GuC
When running the GuC the GPU can't be considered idle if the GuC still has contexts pinned. As such, a call has been added in intel_gt_wait_for_idle to idle the UC and in turn the GuC by waiting for the number of unpinned contexts to go to zero. v2: rtimeout -> remaining_timeout v3: Drop unnecessary includes, guc_submission_busy_loop -> guc_submission_send_busy_loop, drop negatie timeout trick, move a refactor of guc_context_unpin to earlier path (John H) v4: Add stddef.h back into intel_gt_requests.h, sort circuit idle function if not in GuC submission mode Cc: John Harrison <john.c.harrison@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210721215101.139794-16-matthew.brost@intel.com
