Move the variant initialisation entirely to the CRTC init function -
the variant support is really about the CRTC properties than the whole
system, and we want to treat each CRTC individually when we support DT.

Use the number of CRTCs registered to size the vblank arrays rather than
our own count.  Number CRTCs using this as well.  This permits us to
register CRTCs as components in the near future rather than as part of a
single device.

I cannot see a need to provide a DRM_ version of ARRAY_SIZE(), only used
in a few places. I suspect its usage has been spread by copy & paste
rather than anything else.

Let's just remove it for plain ARRAY_SIZE().

Unfortunately this requires a drm-wide change, and I didn't see a sane
way around that. Luckily it's fairly simple, we just need to inline
the respective get_irq implementation from either drm_pci.c or
drm_platform.c.

With that we can now also remove drm_dev_to_irq from drm_irq.c.

The kfifo_put() API changed in 498d319b (kfifo API type safety)
which now results in the wrong pointer being added to the kfifo ring,
which then causes an oops.  Fix this.

Call drm_fb_helper_restore_fbdev_mode() upon last close so that in the
event of the X server crashing, we have some kind of mode restored.

This patch adds support for the pair of LCD controllers on the Marvell
Armada 510 SoCs.  This driver supports:
- multiple contiguous scanout buffers for video and graphics
- shm backed cacheable buffer objects for X pixmaps for Vivante GPU
  acceleration
- dual lcd0 and lcd1 crt operation
- video overlay on each LCD crt via DRM planes
- page flipping of the main scanout buffers
- DRM prime for buffer export/import

This driver is trivial to extend to other Armada SoCs.

Included in this commit is the core driver with no output support; output
support is platform and encoder driver dependent.
