The ioctl DRM_EXYNOS_GEM_MAP_OFFSET and DRM_EXYNOS_GEM_MMAP are removed from
the linux kernel. This patch modifies libdrm and libkms to use drm generic
ioctls instead of the removed ioctls.
v2: The original patch was erroneous. In case the MODE_MAP_DUMB ioctl failed
it would return the retvalue as a void-pointer. Users of libdrm would then
happily use that ptr, eventually leading to a segfault. Change this to
return NULL in that case and also restore the previous behaviour of logging
to stderr.
The other error was that 'bo->vaddr' was never filled with the mapped
buffer address. Hence exynos_bo_map still returned NULL even if the
buffer mapping succeeded.

When division of source and destination width yields the
scaling factor for the x-coordinate, then it should be
source/destination _height_ for y.

The hardware accepts scaling factors formatted in a
fixed-point format. The current macro casts to integer
first, then multiplies by the fp conversion factor.
This does not make any sense. In particular, truly
'fractional' inputs, like 1.5, won't work that way.

The right-bottom register isn't set correctly.
Looks like a copy-and-paste error.

The documentation says fd holds the fd from prime import/export.
However, it isn't actually used, nor is it necessary, so let's just remove
it.

This patch adds library and test application for g2d gpu(fimg2d).
The fimg2d hardware is a 2D graphics accelerator(G2D) that
supports Bit Block Transfer(BitBLT).
The library includes the following primitive drawing operations:
.solid fill - This operation fills the given buffer with
the given color data.
.copy - This operation copies contents in source buffer to
destination buffer.
.copy_with_scale - This operation copies contents in source buffer
to destination buffer scaling up or down properly.
.blend - This operation blends contents in source buffer with
the ones in destination buffer.
And the above operations uses gem handle or user space address
allocated by malloc() as source or destination buffer.
And the test application includes just simple primitive drawing
tests with the above library.
And the guide to test is as the following,
"#exynos_fimg2d_test -s connector_id@crtc_id:mode"
With this above simple command, four primitive drawing operations
would be called step by step and also rendered on the output device
to the given connector and crtc id.

this patch adds libdrm_exynos helper layer that inclues some intefaces
for exynos specific gem and virtual display driver and also adds exynos
module name to modtest and vbltest.
Changelog v2:
- fixed exynos broken ioctl.
the pointer of uint64_t *edid should be removed.
- removed unnecessary definitions.
- added drm prime interfaces.
this feature is used to share a buffer between drivers or memory managers
