Skylake makes primary planes the same as sprite planes and call the
result "universal planes".
This commit emulates a primary plane with plane 0, taking the
opportunity to redefine primary and sprite registers to be identical now
that the underlying hardware is. It also makes sense as plenty of fields
have changed.
v2: Rebase on top of the vma code.

- Drop return values.
- Remove pipe checks since redudant and BUG instead.
- Remove tiling checks and BUG instead.

v5: Misc fixes:
- Fix the fields we need to clear up

Sorry for late. This pull request includes some enhancements
for Exynos drm, new feature supports, cleanups and fixups
like below,
- Consider low power transmission for drm mipi dsi module,
and also add non-continuous clock mode support for Exynos
mipi dsi driver.
- Add Exynos3250 SoC support.
- Enhance and clean up ipp framework and fimc driver.
- Update to use component match support and fix up
de-initialization order.
- Remove a direct mmap interface and relevant stuff specific to
Exynos drm, use drm generic mmap interface instead.
And we will remove the specific interface from userspace
library, libdrm soon.
- Use universal plane which allows to replace fake primary plane
with the real one.
- Some code cleanups and fixups.
* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (40 commits)
drm/exynos: switch to universal plane API

The patch replaces legacy functions
drm_plane_init() / drm_crtc_init() with
drm_universal_plane_init() and drm_crtc_init_with_planes().
It allows to replace fake primary plane with the real one.
Additionally the patch leaves cleanup of crtcs to core,
this way planes and crtcs are cleaned in correct order.

This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific
to Exynos drm and instead uses drm generic mmap.
We had used the interface specific to Exynos drm to do mmap directly,
not to use demand paging which maps each page with physical memory
at page fault handler. We don't need the specific mmap interface
because the drm generic mmap which uses vm offset manager stuff can
also do mmap directly.
This patch makes a userspace region to be mapped with whole physical
memory region allocated by userspace request when mmap system call is
requested.
Changelog v2:
- do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already
set by drm_gem_mmap
- do not include <linux/anon_inodes.h>, which isn't needed anymore.
