The CRTC mode set implementation needs to access the omap_dss_device for
the pipeline display. To do so, it iterates over all pipelines to find
the one that contains an encoder corresponding to the CRTC, and request
the display device from the encoder. That's a very complicated dance
when the CRTC has a direct pipeline pointer already, and the pipeline
contains a pointer to the display device.
Replace the convoluted code with direct access.

On HDMI outputs, CEC support requires notification of HPD signal
deassertion. The HPD signal can be handled by various omap_dss_device
instances in the pipeline, and all of them forward HPD events to the
OMAP4 internal HDMI encoder.
Knowledge of the DSS internals need to be removed from the
omap_dss_device instances in order to migrate to drm_bridge. To do so,
move HPD handling for CEC to the omap_connector.

The omap_dss_device .enable_hpd() and .disable_hpd() are used to enable
and disable hot-plug detection at omapdrm probe and remove time. This is
required to avoid reporting hot-plug detection events before the DRM
infrastructure is ready to accept them, as that could result in crashes
or other malfunction.
Hot-plug event reporting is conditioned by both HPD being enabled
through the .enable_hpd() operation and by the HPD callback being
registered though the .register_hpd_cb() operation. We thus don't need a
separate enable operation if we can guarantee that callbacks won't be
registered too early.
HPD callbacks are registered at connector initialization time, which is
too early to start reporting HPD events. There's however nothing
blocking a move of callback registration to a later time when the
omapdrm driver calls the HPD enable operations. Do so, and remove the
HPD enable operation completely from omap_dss_device drivers.

When an omap_dss_device operation can be implemented in multiple places
in a chain of devices, it is important to find out which device to
address to perfom the operation. This is currently done by calling the
operation on the display device at the end of the chain, and recursively
delagating the operation to the previous device if it can't be performed
locally. The drawback of this approach is an increased complexity in
omap_dss_device drivers.
In order to simplify the drivers, we will switch from a recursive model
to an interative model, centralizing the complexity in a single
location. This requires knowing which operations an omap_dss_device
supports at runtime. We can already test which operations are
implemented by checking the operation pointer, but implemented
operations can require resources whose availability varies between
systems. For instance a hot-plug signal from a connector can be wired to
a GPIO or to a bridge chip.
Add operation flags that can be set in the omap_dss_device structure by
drivers to signal support for operations.

omap_dss_device instances have two ops structures, omap_dss_driver and
omap_dss_device_ops. The former is used for devices at the end of the
pipeline (a.k.a. display devices), and the latter for intermediate
devices.
Having two sets of operations isn't convenient as code that iterates
over omap_dss_device instances need to take them both into account.
There's currently a reasonably small amount of such code, but more will
be introduced to move the driver away from recursive operations. To
simplify current and future code, move all operations that are not
specific to the display device to the omap_dss_device_ops.
