Add DRM prime import support to the armada-drm buffer manager. This
allows dma_bufs to be imported into armada-drm for display.

Whether a bo can be re-used or not depends whether we have flink'd it,
whether it was imported from a global name, or imported from a fd.

Provide an API to allow libdrm-armada's internal BO cache to be reaped.
This API returns TRUE if there are still BOs in the cache which may be
reaped at a later time, which allows users to schedule further reaps.

We no longer need this function, because we can do everything via the
dma_buf passing methods. So, get rid of this.

With flink support, we really need to know whether a particular handle
relates to an object we already know about. Store the buffer objects
in a hash table using the handle as a key. Do the same with DRM
names.

drm_armada_bo_phys() is no longer necessary with dmabuf support, so
drop it from the library. Also get rid of the bo "phys" member.

Get rid of unused members in the create ioctl, and re-shuffle the
pwrite ioctl to avoid any ABI issues.

As this is not specific to Armada 510 (Dove) devices, but also appears
on other Marvell Armada devices, use "armada" as the name rather than
"dove".
