Bug#619019: i915: Remove 'pipe A force' quirk for 855GM and 845G
Applying this quirk to the 855GM in all systems causes regressions
(Debian bugs #493096, #619019). Instead, apply the quirk to specific
models as listed in the old X driver.
I don't see any explanation for this quirk being applied to the 845G,
except perhaps that VT switching used to hang if pipe A was turned
off. However, that seems to be a problem only when using UMS. So
remove the quirk for the 845G as well.

Needs people to test it, as I can't.
