[Intel-gfx] [RFC 4/4] drm/i915/gen9: Skip debugfs cursor output for universal plane platforms

[Matt Roper]

The universal plane acting as a cursor for userspace purposes still
shows up farther down the output so we still have all the important
information.

Refactor the cursor printing out to a new function while we're at it;
the nesting was getting a bit deep.
