ORIGEN board is fitted with 7" LCD panel HV070WSA. The pixel
resolution of the LCD panel is 1024x600.

The patch is rebased on [1]. But for proper working of LCD on ORIGEN,
following patches are needed.

a. ARM: EXYNOS4: Add PWM backlight support on Origen

b. ARM: EXYNOS4: Configure MAX8997 PMIC for Origen
