This patch replaces this panel's display mode with the display timing

Instead of duplicating the code, make use of the newly introduced atomic
state duplicate and destroy helpers. This allows changes to the base
atomic state handling to automatically propagate to the Tegra driver and
thereby prevent breakage resulting from both copies going out of sync.
Signed-off-by: NThierry Reding <treding@nvidia.com>

Drivers that subclass CRTC, plane or connector state need to carefully
duplicate the code that the atomic helpers have. This is bound to cause
breakage eventually because it requires auditing all drivers and update
them when code is added to the helpers.

In order to avoid that, implement new helpers that perform the required
steps when copying and destroying state. These new helpers are exported
so that state-subclassing drivers can use them. The default helpers are
implemented using them as well, providing a single location that needs
to be changed when adding to base atomic states.

The legcy colorkey ioctls are only implemented for sprite planes, so
reject the ioctl for primary/cursor planes. If we want to support
colorkeying with these planes (assuming we have hw support of course)
we should just move ahead with the colorkey property conversion.
