drm/exynos: fix display power call issue.
Changelog v3:
make exynos_drm_display_power function use exynos_drm_best_encoder
function instead of connector->encoder to get a valid encoder.
connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB
request, connector->encoder is NULL so fix this issue.
Changelog v2:
remove static prefix so that exynos_drm_best_encoder function
could be called by other modules.
Changelog v1:
this patch fixes the issue that display power callback isn't called.
with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL
so display_ops->power_on() wouldn't be called so this patch makes
exynos_drm_best_encoder function to be used to get a valid encoder
of each connector.
