drm/xe: Increase TDF timeout

Browse source

[ Upstream commit eafb6f6209 ]

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.
