The hdmi outputs black screen only even though under the hood Xorg and
framebuffer console are fine : devices found and initialized, but
not a pixel out.
Commit 93bca243ec96 ("drm/exynos: remove struct exynos_drm_manager")
changed the call order of mixer_initialize with regards to
exynos_drm_crtc_create.
This changes breaks hdmi out on Odroid U2 (linux-next with added
Marek Szyprowski v4 hdmi patchset from linux-samsung-soc ML).
Restore the previous call ordering get hdmi to ouput proper pixels:
ie call mixer_initialize first then exynos_drm_crtc_create.
Fixes: 93bca243ec96 ("drm/exynos: remove struct exynos_drm_manager")
