drm/i915: Re-enable GGTT earlier after GPU reset
Inside i915_gem_reset(), we start touching the HW and so require the
low-level HW to be re-enabled, in particular the PCI BARs.
Fixes: 7b6da818d86f ("drm/i915: Restore the kernel context after a GPU
reset on an idle engine")
References: 0db8c9612091 ("drm/i915: Re-enable GTT following a device
reset")
Testcase: igt/drv_hangman #i915g/i915gm
