This reverts commit 446f2545. I've left the masking in the pageflip code since that seems to be some useful piece of preemptive robustness. Iirc I've merged this patch under the assumption that the BIOS leaves some random gunk in the lower bits and gets unhappy if we trample on them. We have quite a few case like this, so this made sense. Now I've just learned that there's actual hardware features bits in the low 12 bits, and the kernel needs to preserve them to allow a userspace blob to do its job. Given Dave Airlie's clear stance on userspace blob drivers I've quickly chatted with him and he doesn't seem too happy. So let's revert this. If there are indeed bits that we must preserve in this range then we can ressurrect this patch, but with proper documentation for those bits supplied. And we probably also need to think a bit about interactions with our driver.

Now we have this everywhere. Next up would be to wire up the DP hotplug pin to speed up panel power sequencing for eDP panels ... I've decided to leave the has_aux_irq logic in the code, it should come handy for hw bringup. For testing/fail-safety the dp aux code already has a timeout when waiting for interrupts to signal completion and screams rather loud if they don't arrive in time. Given that we need a real piece of hw to talk to anyway this is probably as good as it gets. v2: Don't check the dp aux channel bits on i965 machines, they have a different meaning there.

Useful for dp aux to work better. Also stop enabling the port A hotplug event - eDP panels are expected to fire that interupt and we're not really ready to deal with them. This is consistent with how we handle port A on ilk-hsw. The more important bit is that we must delay the enabling of hotplug interrupts until all the encoders are fully set up. But we need irq support earlier than that, hence hotplug interrupts can only be enabled in the ->hpd_irq_setup callback. v2: Drop the _HOTPLUG, it isn't (Ville).

- Pipe underrun can't just be enabled, we need some support code like on ilk-hsw to make this happen. So drop it for now. - CRC error is a special mode of the CRC hardware that we don't use, so again drop it. Real CRC support for bdw will be added later. - All the other error bits are about faults, so rename the #define and adjust the output. v2: Use pipe_name as pointed out by Ville.
