[PATCH] drm/exynos: dsi: remove unnecessary pm interfaces

[Inki Dae]

Exynos drm driver is a single driver so pm operation
for kms drivers should be done by connector->dpms
at top level driver.

If kms driver has its own pm interfaces, single driver model
would be broken so this patch removes unnecessary pm interfaces
from dsi driver.
