[Intel-gfx] [PATCH v2 00/19] Remove depencies on staged config for atomic transition

[Ander Conselvan de Oliveira]

Here's v2 with most of the comments from Daniel addressed. I didn't change
the zeroing of the crtc_state to the duplicate state function, since it
causes problems when we add the state of a crtc that isn't going through
a modeset. Specifically, this would cause the code that decides whether
pipes B and C can be enabled at the same time to fail, since the number
of fdi lanes would be zero.

The other concerns I raised with v1 are also addressed. I tested this on
IVYBRIDGE using pipes B & C, and the load detect code path using Daniel's
patch that adds the i915.load_detect_test parameter.

Thanks,
Ander
