There are display panels which demands that the sync signal is driven on
different edge than the pixel data.
With the syncclk-active property we can specify the clk edge to be used to
drive the sync signal. When the property is missing it indicates that the
sync is driven on the same edge as the pixel data.

omap_plane_atomic_update() does WARN_ON() if dispc rejects the given
plane config. Change that to dev_err() to lessen the possible spam.

To fix this correctly, the plane setup needs much more work by creating
a check function for dispc setup, so that we could reliably check the
config in atomic_check, instead of only noticing the problem when
programming dispc.

Clean up omap_plane_atomic_check() with:

- Check state->fb first. If no fb, return 0.
- use drm_atomic_get_existing_crtc_state() instead of
  drm_atomic_get_crtc_state()
Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

I sometimes see:

[drm:drm_framebuffer_remove [drm]] *ERROR* failed to reset crtc ed2a6c00
when fb was deleted: -22

which comes from drm_framebuffer_remove() when it's disabling the crtc
with zeroed drm_mode_set.

The problem in omap_plane_atomic_check() is that it will use those
zeroed fields to verify if the setup is correct.

This patch makes omap_plane_atomic_check() return 0 if the crtc is
disabled.

The current default of always using the performance power state leads
to increased power consumption of mobile devices, which have a dedicated
battery power state. Switch between the performance and battery power
state automatically, dpending on the current AC power status, when the
user asked for the balanced power state.

The user can still override this logic by asking for the performance
or battery power state explicitly.
