Souza, Jose Aug. 9, 2018, 12:15 a.m. UTC 
When loading the driver
i915_load_modeset_init()->intel_modeset_setup_hw_state() do the
counter part call of intel_power_domains_init_hw() calling
intel_display_set_init_power(false).
The problem is i915_load_modeset_init() is not executed when display
is disabled, so moving it to i915_driver_load().
Also calling intel_display_set_init_power(false) in
__intel_display_resume() as it would be executed by calling
intel_modeset_setup_hw_state().
