drm/exynos: ipp: Add IPP v2 framework

This patch adds Exynos IPP v2 subsystem and userspace API.

New userspace API is focused ONLY on memory-to-memory image processing.
The two remainging operation modes of obsolete IPP v1 API (framebuffer
writeback and local-path output with image processing) can be implemented
using standard DRM features: writeback connectors and additional DRM planes
with scaling features.

V2 IPP userspace API is based on stateless approach, which much better fits
to memory-to-memory image processing model. It also provides support for
all image formats, which are both already defined in DRM API and supported
by the existing IPP hardware modules.

The API consists of the following ioctls:
- DRM_IOCTL_EXYNOS_IPP_GET_RESOURCES: to enumerate all available image
processing modules,
- DRM_IOCTL_EXYNOS_IPP_GET_CAPS: to query capabilities and supported image
formats of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_GET_LIMITS: to query hardware limitiations for
selected image format of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_COMMIT: to perform operation described by the
provided structures (source and destination buffers, operation rectangle,
transformation, etc).

The proposed userspace API is extensible. In the future more advanced image
processing operations can be defined to support for example blending.

Userspace API is fully functional also on DRM render nodes, so it is not
limited to the root/privileged client.

Internal driver API also has been completely rewritten. New IPP core
performs all possible input validation, checks and object life-time
control. The drivers can focus only on writing configuration to hardware
registers. Stateless nature of DRM_IOCTL_EXYNOS_IPP_COMMIT ioctl simplifies
the driver API. Minimal driver needs to provide a single callback for
starting processing and an array with supported image formats.
