kms_frontbuffer_tracking: Increase the time we wait for PSR.

Browse Source 
With commit (drm/i915: Delay first PSR activation.) in kernel
PSR might take a bit longer to really activate after the modeset.
The first PSR activation after modeset is taking 5 times the panel
power cycle delay time, which is 600ms for our machines here.
So timeout here needs to be a minimum of 3s. However let's use
5s as the safe value in case we find machines with higher power
cycle delay.

Since we do a lot of assert(psr_disabled), this commit is increasing
the time it takes to run the whole set of PSR tests by a few minutes,
which had been reduced by commit f4db3b18841
("kms_frontbuffer_tracking: reduce the PSR wait timeout to 2s").
