[PATCH 1/8] drm/xe: Add GT oriented drm_printers

[Michal Wajdeczko]

Instead of using generic drm_err_printer() that just adds static
prefix, or drm_info_printer() that outputs only device name, add
new helpers that create dedicated drm_printers that use our GT
oriented xe_gt_err() and xe_gt_info() functions.
