    drm/exynos: separate dpi from fimd

    The patch separates dpi related routines from fimd.

    Changelog v2:
    - Rename ctx->dpi to ctx->display

The good commit(000cc9204e5a71dab1aafac1312b209a87077bdd) on (drm-intel-fixed) can be found on (drm-intel-next-queued) branch, but BSW did not show up screen after start kernel after compiled (drm-intel-next-queued:000cc9204e5a71dab1aafac1312b209a87077bdd )

Regression:
--------------------------
Should be, but cannot do bisect, only find good commit in (drm-intel-fixed) branch, (drm-intel-next-queued) and (drm-intel-nightly) latest commit all fail.

Reproduce steps:
--------------------------
1. Boot into system
2. xinit &
3. sleep 1;xset dpms force off
4. Resume dpms though click the keyboard
will observe backlight till off, and there is x window shadow in the display
