Subject: drm: Remove internal setup of struct

Patch-mainline: v5.7-rc1

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
