drm/i915/gt: Force the GT reset on shutdown
commit 7c4541a37bbbf83c0f16f779e85eb61d9348ed29 upstream.
Before we return control to the system, and letting it reuse all the
pages being accessed by HW, we must disable the HW. At the moment, we
dare not reset the GPU if it will clobber the display, but once we know
the display has been disabled, we can proceed with the reset as we
shutdown the module. We know the next user must reinitialise the HW for
their purpose.
