    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"
    Changing the timeout value from 150 to 500 could help avoid these error messages
    in the stress tests.
    
    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.
