libkms should not be used, because it imposes limitations on the DRM
API, especially regarding bpp and stride. Instead the DRM IOCTL should
be used directly.
Switch from libkms to the IOCTL interface. Set bpp and height for
framebuffer allocation to properly handle planar video formats.

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.
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.
