Subject: [PATCH v3 2/2] ARM: Exynos: Use lcd power control driver for lcd panel

The Hydis hv070wsa lcd panel used with the Origen board uses a gpio
for reset and the Vcc supply to the panel can be controlled using
a voltage regulator. Switch to using the lcd power control driver
for controlling the power to the lcd panel.
