drm/i915: Remove unused underrun irq/reporting bits
Underrun recovery was defeatured and was never brought into usage.
Thus we can remove the underrun recovery interrupt/reporting
register bits and related logic introduced to detect/report soft,
hard, port underruns.
Essentially this is a revert of the commit 8bcc0840cf7c
("drm/i915/xelpd: Enhanced pipe underrun reporting") which originally
added this functionality. Also note that PIPE_STATUS_UNDERRUN bit in
PIPESTATUS still stays relevant but we would move back to not
clearing this sticky bit as we are not using any information from
this register.
v2: Extend commit message to add more details (Matt Roper)
v3: Fix the old commit mention in commit message
