drm/i915: Fixup pfit disabling for gen2/3
The recent rework of the pfit handling didn't take into account that
the panel fitter is fixed to pipe B:

drm/i915: disable shared panel fitter for pipe
Fix this up by properly computing the pipe the pfit is on. Also
extract the logic into its own function, add a debug assert to check
that the pipe is off (mostly just documentation) and add some debug
output.
If pipe A was disabled after pipe B was set up, the panel fitter will
be disabled. Now most userspace doesn't do modesets in this order,
which is why I couldn't ever reproduce this and why it took me so long
to figure out.
We really need hw state readout and check support for the pannel
fitter ...
