bf6f1fa62e drm/mcde: Drop drm_gem_prime_export/import
They're the default.

Aside: Would be really nice to switch the others over to
drm_gem_object_funcs.

0424fdaf88 drm/prime: Actually remove DRIVER_PRIME everywhere
Split out to make the functional changes stick out more.

All places where DRIVER_PRIME was used have been removed in previous
patches already.

v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE.

v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE.

v4: Don't add a space in i915_drv.c (Sam)

v5: Add note that previous patches removed all the DRIVER_PRIME users
already (Emil).

v6: Fixupe ingenic (new driver) while applying.

bb5ce9a017 drm/mcde: Fix an uninitialized variable
We never set "vblank" to "false".

Current versions of GCC will initialize it to zero automatically at
certain optimization levels so that's probably why this didn't show up
in testing.

5fc537bfd0 drm/mcde: Add new driver for ST-Ericsson MCDE
This adds a new DRM driver for the ST-Ericsson Multi Channel
Display Engine, MCDE display controller.

This hardware has three independent DSI hosts and can composit
and display several memory buffers onto an LCD display. It
was developed for several years inside of ST-Ericsson and
shipped with a few million mobile phones from Sony and Samsung,
as well as with the Snowball community development board.

The driver is currently pretty rudimentary but supports a
simple framebuffer so we can get penguins and graphics when
using these SoCs.
