verify-kernel-boot-log: add more display information

Searching for "(dis)connected" in i915_display_info shows useful connector info. Also show /sys/class/drm/ and /sys/kernel/debug/dri/0/, this will be useful for DRM_XE, see thesofproject/kconfig#91 Signed-off-by: Marc Herbert <[email protected]>
