drm/xe: Enlarge the invalidation timeout from 150 to 500
There are error messages like below that are occurring during stress testing:
"[ 31.004009] xe 0000:03:00.0: [drm] ERROR GT0: Global invalidation timeout"
Previously it was hitting this 3 with 1000 executions of warm reboot.
After raising it to 500, 1000 warm reboot executions passed and it didn't
fail.
Due to the way xe_mmio_wait32() is implemented, the timeout is able to expire
early when the register matches the expected value due to the wait increments
starting small. So, the larger timeout value should have no effect during
normal use cases.
