drm/exynos: fimd: remove unnecessary waiting vblank routine

The exynos_drm_crtc_dpms() waits until pended page flip

manager->ops->dpms() when mode is DRM_MODE_DPMS_OFF.
The fimd_dpms() is one of manager->ops->dpms()s and
finally calls fimd_window_suspend().
But there is no active window and vblank is already off
when it is called.
So addtional waiting vblank is not necessary any more.

Sub drivers could be probed before resources, clock, regulator,

drm core waits until all resources are ready and sub drivers are
probed correctly.

- Make sure that exynos drm core tries to bind sub drivers only in case that
they have a pair: crtc and encoder/connector components should be a pair.
- Remove unnecessary patch:

drm/exynos: use 4WORD dma burst length for small fbs

In case of exynos, setting dma-burst to 16Word causes permanent
tearing for very small buffers, e.g. cursor buffer. Burst Mode
switching, which is based on overlay size is not recommended as
overlay size varies a lot towards the end of the screen. This
causes unstable DMA which results into tearing again.

Rendering small buffers with lower burst size doesn't
cause any noticable performance overhead. 128 pixel width is
selected based on mulitple experiments with exynos5 SoCs.
