[Intel-gfx] ✗ Fi.CI.BAT: warning for drm/i915: Respect num_pipes when install or reset display IRQ

[Wang, Elaine]

This patch shouldn't impact on platforms that have non-zero num_pipes. The warning happened to snb, which has non-zero num_pipes according to dmesg log "[drm:intel_modeset_init [i915]] 2 display pipes available" in https://intel-gfx-ci.01.org/CI/Patchwork_3383/fi-snb-2520m/dmesg-before.log. So the warning isn't a regression caused by this patch.

According to the error message in dmesg log, it looks like it's the same issue reported by Bug 98228 - [BAT IVB] HDMI *ERROR* EDID checksum is invalid ( https://bugs.freedesktop.org/show_bug.cgi?id=98228)

[  413.875957] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 63

Thanks,
Elaine
