drm/xe: Increase TDF timeout
There are some corner cases where flushing transient
data may take slightly longer than the 150us timeout
we currently allow. Update the driver to use a 300us
timeout instead based on the latest guidance from
the hardware team. An update to the bspec to formally
document this is expected to arrive soon.
