<pre>I tested on latest drm-intel-nightly(8980a4380b606860ba0165ed0156a64e79109677)
and latest drm-intel-next-queued(a6f9a026761c9c9440bb6a387e84a47d40290176),
these sub cases passed.

drm/i915: Fix DEIER and GTIER collecting for BDW.
BDW has many other Display Engine interrupts and GT interrupts registers.
Collecting it properly on gpu_error_state.

DEIER and GTIER that doesn't exist on BDW anymore. This was causing
unclaimed register messages:

v2: Fix small issues of first version and don't read DEIER regs when pipe's
power well is disabled
v3: bikeshed accepted: use enum pipe pipe instead of int i for pipe
interection
