drm/i915: Disable all outputs early, before KMS takeover
If the outputs are active and continuing to access the GATT when we
teardown the PTEs, then there is a potential for us to hang the GPU.
The hang tends to be a PGTBL_ER with either an invalid host access or
an invalid display plane fetch.
v2: Reorder IRQ initialisation to defer until after GEM is setup.

# note that this doesn't fix the underlying problem of the
PGTBL_ER and pipe underruns being reported immediately upon
init on his 965GM MacBook
