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.

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.
