I wasn't able to find what's missing in the DISP1 pd definition so posted
a revert [0] to "ARM: dts: add display power domain for exynos5250".

Kukjin,

Please ignore $subject and pick [0] instead.

This will avoid Snow and Spring display to stop working and later the PD
can be added again once we know what was missing there.

Best regards,
Javier
