drm/i915/gt: Pull GT initialisation under intel_gt_init()

2019-12-22T12:51:32+00:00

Begin pulling the GT setup underneath a single GT umbrella; let intel_gt take ownership of its engines! As hinted, the complication is the lifetime of the probed engine versus the active lifetime of the GT backends. We need to detect the engine layout early and keep it until the end so that we can sanitize state on takeover and release.
