The calculation of the offset table was done base on a plane size
estimation. This does not always work. Instead, use memory offset the
same we as it's implement in GstVideoMeta map functions.
Without setting the DRM_CLIENT_CAP_UNIVERSAL_PLANES capability bit, only
overlay planes are made available for compatibility with legacy clients.
But if a CRTC doesn't have an overlay plane associated, then kmssink is
not able to find a plane for the CRTC and the pipeline will fail, i.e:
ERROR kmssink gstkmssink.c:482:gst_kms_sink_start:<kmssink0> Could not find a plane for crtc
If no overlay planes were found for a given CRTC, fallback to universal
planes so DRM will also return primary planes that can be used instead.

This patch adds a plane-id property to the kmssink element so a specific
plane can be used in case that a CRTC has only a primary plane associated.

This patch requests for drmModePageFlip() for the used CRTC, if the kernel
module suppports async page flip. If it does not, the element requests for a
vblank event. A GstPoll waits for the event to happen.

This patch will enable the import of dmabufs into a KMS buffer using
the PRIME kernel interface.
If the driver does not support prime import, the method is skipped.
It has been tested with a Freescale I.MX6 board.

This is simple video sink that use libdrm/libkms API to render frames.
The element uses planes to render through drmModeSetPlane().
It has been tested in an Exynos4412 board and in a Freescale I.MX6 board.
