[PATCH 3/5] drm/i915: check for more ASLC interrupts

[Paulo Zanoni <przanoni@gmail.com>]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

Sometimes I see the "non asle set request??" message on my Haswell
machine, so I decided to get the spec and see if some bits are missing
from the mask. We do have some bits missing from the mask, so this
patch adds them. But I still see the "non asle set request??" message
on my machine :(

Also use the proper ASLC name to indicate the registers we're talking
about.
