kms_frontbuffer_tracking: reduce the PSR wait timeout to 2s

Browse Source 
PSR only takes up to 100ms to be enabled, but we were using 5000ms
timeouts. The problem with PSR is that the MMAP_GTT tests have to
assert that PSR is disabled and stays disabled during the whole
timeout, so that 5s cost is a little to high when we consider that we
do the full 5s wait 74 times when running kms_frontbuffer_tracking
--psr-only.

By reducing to 2s we still make sure we're safe, since we're waiting
20x the time PSR needs to get reenabled, and we reduce the runtime of
running kms_frontbuffer_tracking --psr-only from 14m10s to 10m29s.
