[Intel-gfx] [PATCH v2 00/21] drm: Clean up VBLANK callbacks in struct drm_driver

VBLANK handlers in struct drm_driver are deprecated. Only legacy,
non-KMS drivers are supposed to used them. DRM drivers with kernel
modesetting are supposed to use VBLANK callbacks of the CRTC
infrastructure.
This patchset converts all DRM drivers to CRTC VBLANK callbacks and
cleans up struct drm_driver. The remaining VBLANK callbacks in struct
drm_driver are only used by legacy drivers.
Patches 1 and 3 prepare the DRM infrastructure. These patches add
get_scanout_position() to struct drm_crtc_helper_funcs, get_vblank_timestamp()
to struct drm_crtc_funcs, and add helpers for the new interfaces. Patch 2
changes the VBLANK code to evaluate vblank_disable_immediate in struct
drm_device. This simplifies the integration of CRTC VBLANK callbacks in
patch 3. If necessary, a future patch could move vblank_disable_immedate
to struct drm_crtc, so that high-precision VBLANKs could be enabled on a
per-CRTC basis.
Patches 4 to 20 convert drivers over.
In patch 21, all VBLANK callbacks are removed from struct drm_driver, except
for get_vblank_counter(), enable_vblank(), and disable_vblank(). These
interfaces are moved to the legacy section at the end of the structure. Old
helper code is now unused and being removed as well.
To cover all affected drivers, I build the patchset in x86, x86-64,
arm and aarch64. I smoke-tested amdgpu, gma500, i915, radeon and vc4 on
respective hardware.
v2:
* reorder patches so the i915 can be converted without duplicating
helper code.
* merged cleanup patches
* changed VBLANK function signatures in amdgpu
