[intel] Get vblank pipe from irq_mask_reg instead of hardware enable reg
With the interrupt enable/disable using only the mask register, it was wrong
to use the enable register to detect which pipes had vblank detection

MSI machines smack the hardware during the interrupt handler, it is more
efficient and more correct to use the local copy.

sysfs registration/teardown fixups
A check in drm_sysfs_connector_remove was supposed to allow it to be called
even with unregistered objects, to make cleanup paths a little simpler.
However, device_is_regsitered didn't always seem to return what we thought it
would, so we'd sometimes end up leaving objects lying around rather than
unregistering them.
Fix this situation up by requiring devices to be registered before being
removed. Any problems resulting from this change should be easier to track
down than the alternative (which is leaving kobjects registered after unload).

This will be used by the X Server for VT switch.
