[PATCH 2/2] drm/exynos: use KMS version of DRM vblanks functions

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan at collabora.co.uk>

Get rid of legacy DRM vblank function that are less clear to use.
The new only basically requires only the crtc as paramenters.

It also clean ups exynos_drm_crtc_finish_pageflip() parameters as a
consequence.
