Replace the use of drm_plane_helper_check_update() with
drm_plane_helper_check_state() since we have a plane state.
Rockchip looks to handling plane clipping rather well already
(unlikje most arm drm drivers) so there are no function changes
here.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

Currently the driver calls drm_dev_register() directly after allocating
the DRM device and then continues with further initialization. This is
incorrect, because drm_dev_register() is supposed to be called after all
initialization is done. This problem was masked by the fact that
drm_dev_register() did not use to do anything special before, but
recently it started to call drm_connector_register_all(), which leads to
a crash if the driver is not fully initialized.
This patch fixes the problem by moving the call to drm_dev_register() to
the end of the initialization sequence and also removing the, now
unnecessary, call to drm_connector_register_all() from driver code.

It's not permissible to look at plane->state from interrupt context,
since doing that would need the irq handler to acquire the
plane->mutex lock.
The other problem is that if we pipeline updates using the new
nonblocking atomic helpers new state gets commit before the irq
handler fires, resulting in a lost event.
Fix both issues by caching the necessary values in vop_win, protected
by dev->event_lock.

drm: Rework vblank-wait handling to allow interrupt reduction.
to stay backwards-compatible with old UMS code that didn't even tell
the kernel when it did a modeset, so that the kernel could
save/restore vblank counters. At worst this means vblanks will be
somewhat funky on a setup that very likely no one still runs.
So let's just nuke it.
Plan B would be to set it unconditionally in drm_vblank_init for kms
drivers, instead of in each driver separately. So if this patch breaks
anything please only restore the hunks in drmP.h and drm_irq.c, plus
add a check for DRIVER_MODESET in drm_vblank_init.
Stumbled over this in a discussion on irc with Chris.

drm_gem_object_lookup() has never required the drm_device for its file
local translation of the user handle to the GEM object. Let's remove the
unused parameter and save some space.

Ofc I promise just a few leftovers for drm-misc and somehow it's the
biggest pull. But really mostly trivial stuff:
- MAINTAINERS updates from Emil
- rename async to nonblock in atomic_commit to avoid the confusion between
nonblocking ioctl and async flip (= not vblank synced), from Maarten.
Needs to be regened with newer drivers, but probably only after -rc1 to
catch them all.
- actually lockless gem_object_free, plus acked driver conversion patches.
All the trickier prep stuff already is in drm-next.
- Noralf's nice work for generic defio support in our fbdev emulation.
Keeps the udl hack, and qxl is tested by Gerd.

After async atomic_commit callback, drm_atomic_clean_old_fb will
clean all old fb, but because async, the old fb may be also on
the vop hardware, dma will access the old fb buffer, clean old
fb will cause iommu page fault.
Reference the fb and unreference it when the fb actuall swap out
from vop hardware.

Some rockchip vop not support iommu, need use non-iommu
buffer for it. And if we get iommu issues, we can compare
the issues with non-iommu path, that would help the debug.
