From: Gustavo Padovan gustavo.padovan@collabora.co.uk

Run dpms operations through the atomic intefaces. This basically removes the .dpms() callback from econders and crtcs and use .disable() and .enable() to turn the crtc on and off.

v2: Address comments by Joonyoung: - make hdmi code call ->disable() instead of ->dpms() - do not use WARN_ON on crtc enable/disable

v3: - Fix build failure after the hdmi change in v2 - Change dpms helper of ptn3460 bridge

v4: - remove win_commit() call from .enable()

v5: - move .atomic_check() to the atomic PageFlip patch, and transform it in .atomic_begin()

To follow more closely the new atomic API we split the dpms() helper into the enable() and disable() helper to get exactly the same semantics.
