[Intel-gfx] [PATCH v3 01/22] drm: Remove internal setup of struct drm_device.vblank_disable_immediate

[Thomas Zimmermann]

VBLANK interrupts can be disabled immediately or with a delay, where the
latter is the default. The former option can be selected by setting
get_vblank_timestamp and enabling vblank_disable_immediate in struct
drm_device. Simplify the code in preparation of the removal of struct
drm_device.get_vblank_timestamp.

v3:
	* remove internal setup of vblank_disable_immediate
