Krzysztof Kozlowski 1c363c7ccc drm/exynos: Enable DP clock to fix display on Exynos5250 and other
After adding display power domain for Exynos5250 in commit
2d2c9a8d0a ("ARM: dts: add display power domain for exynos5250") the
display on Chromebook Snow and others stopped working after boot.

The reason for this suggested Andrzej Hajda: the DP clock was disabled.
This clock is required by Display Port and is enabled by bootloader.
However when FIMD driver probing was deferred, the display power domain
was turned off. This effectively reset the value of DP clock enable
register.

When exynos-dp is later probed, the clock is not enabled and display is
not properly configured:

exynos-dp 145b0000.dp-controller: Timeout of video streamclk ok
exynos-dp 145b0000.dp-controller: unable to config video

Fixes: 2d2c9a8d0a ("ARM: dts: add display power domain for exynos5250")
