[Intel-xe] [PATCH 10/15] drm/i915/display: add intel_display_driver_early_probe()

[José Roberto de Souza]

From: Jani Nikula <jani.nikula at intel.com>

Add intel_display_driver_early_probe() as the early probe call to
replace intel_init_display_hooks(). The latter will be "demoted" to
setting up hooks in intel_display.c only.
