Merge tag 'exynos-drm-fixes-for-v4.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes

Fixups
- Fix several problems to IPPv2 merged to mainline recentely.
  . An align problem of width size that IPP driver incorrectly
    calculated the real buffer size.
  . Horizontal and vertical flip problem.
  . Per-plane global alpha for XRGB modes.
  . Incorrect variant of the YUV modes.
- Fix plane overlapping problem.
  . The stange order of overlapping planes on XRGB modes
    by setting global alpha value to maximum value.

Cleanup
- Rename a enum type, drm_ipp_size_id, to one specific to Exynos,
  drm_exynos_ipp_limit_type.
- Replace {un/reference} with {put,get} functions.
  . it replaces several reference/unreference functions with Linux
    kernel nameing standard.
