drm/xe: Increase global invalidation timeout to 1000us

Browse source

commit e5ae8d1eb0 upstream.

The previous timeout of 500us seems to be too small; panning the map in
the Roll20 VTT in Firefox on a KDE/Wayland desktop reliably triggered
timeouts within a few seconds of usage, causing the monitor to freeze
and the following to be printed to dmesg:

[Jul30 13:44] xe 0000:03:00.0: [drm] *ERROR* GT0: Global invalidation timeout
[Jul30 13:48] xe 0000:03:00.0: [drm] *ERROR* [CRTC:82:pipe A] flip_done timed out

I haven't hit a single timeout since increasing it to 1000us even after
several multi-hour testing sessions.
