When fastbooting, we read out the pipe timings early on, and then in a
panel fitted config, disable the fitter later. But we weren't updating
the pipe src h/w, which meant the mouse cursor was clipped to the
pfitted size rather than the native size set later. Fix that up so the
cursor is visible in the new mode.

The bug report doesn't say anything about the pipe config state
checker being unhappy. Are we missing a call to the checker for
fastboot somewhere to catch this stuff?

Yeah I think so. Cooking up a separate patch for that now...

Ah no, we do have a check there. I guess since we never updated it we
were comparing two stale values?

The hw values should reflect what we're writing into the PF_WIN_*
registers, but the sw side should be stale. I think a dpms on/off
should trigger a checker warning, but having one after each
fastboot'ed setCrtc might be benefitial in general. I just want to
make sure that we don't have more dragons lurking ...
