nvrm: move stale wait checking into the kerneltegra-11.2.6
The kernel now receives wait tracking data (similar to gathers and
relocs) and compares the current syncpt with the threshold value.
If it's old, it gets a kernel mapping and rewrites the method data
to use a kernel reserved syncpt that is always 0 (so trivially pops
when seen by the HW).

Bug 803452
Note: reset the author in this commit to fix a email addr problem
and since from the latest/last cherry pick there was a reworking
of the code to be compatible with different user space versions
it also seemed reasonable.
