CHROMIUM: drm/rockchip: Add GEM create ioctl support

Rockchip Socs have GPU, we need allocate GPU accelerated buffers.
So add special ioctls GEM_CREATE/GEM_MAP_OFFSET to support
accelerated buffers.

But the specific GRF register address is different between RK3288

FROMLIST: drm/rockchip: vop: Fix vop crtc cleanup

This fixes a few problems in the vop crtc cleanup (handling error
paths and cleanup upon exit):

* The vop_create_crtc() error path had an unsafe version of the
  iterator used for iterating over all planes (though it was
  destroying planes in the iterator so should have used the safe
  version)

* vop_destroy_crtc() - wasn't calling vop_plane_destroy(), which made
  slub_debug unhappy, at least if we ended up running this due to a
  deferred probe.

* In vop_create_crtc() if we were missing the "port" device tree node
  we would fail but not return an error (found by code inspection).

Fix these problems.

This can be triggered somewhat reliably with:

modetest -M rockchip -v -s ...

Add a preclose hook to the driver so that we can discard any pending
vblank events when the device is closed.

drm/rockchip: analogix_dp: add rk3399 eDP support

RK3399 and RK3288 shared the same eDP IP controller, so this time we
just need to append the RK3399 compatible name to analogix_dp documentation
and driver code.
