[PATCH v2 14/23] drm/exynos: remove wrappers for phy_power_{on,off}

[Gustavo Padovan]

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

phy_power_on() and phy_power_off() already checks for NULL pointer.
This patch removes the wrappers exynos_dp_phy_init() and
exynos_dp_phy_exit() since the only think they were doing was a check for
NULL phy.
