This removes the need to access the global DISPC private data in those
functions (both for the current accesses and the future ones that will
be introduced when allocating the DISPC private data dynamically).
In order to allow the omapdrm side to call the dispc_ops with a DISPC
pointer, we also introduce a new function dss_get_dispc() to retrieve
the DISPC corresponding to the DSS.

Remove the global dispc ops variable by storing it in the dss_device
structure.

The dss_device is the top-level component in the omapdss driver. Give
the omapdrm driver access to the dss_device pointer in order to obtain
pointers to all other components from it. This requires a new global
variable in the omapdss driver that will be removed when merging the
omapdrm and omapdss drivers, but will already allow removal of several
other global variables.
As this partly duplicates the omapdss_is_initialized() API, reimplement
it as an inline function wrapping omapdss_get_dss().

Having the filename in the header serves little purpose and is
often wrong after renames as it is here in several places, just
drop it from all omapdrm files.
While we are here unify the copyright tags to the TI recommended style.

When omapdss is loaded (all core components are in place) create a list of
devices used in the display graph. This list later can be used by omapdrm
via the omapdss_stack_is_ready() function to check that these components
are loaded. Based on this information, omapdrm can defer probe in case when
the omapdss stack is not ready yet.

We want to change the dispc API from plain functions to a struct with
functions pointers, so that omapdrm can call either omapdss or omapdss6
depending on the platform.
This patch adds 'struct dispc_ops' and adds functions to omapdss-base
to set and get the ops.

omapdss_is_initialized() is used to find out if omapdss has been probed
successfully. This patch moves the related code to the common
omapdss-base module, so that the same support will be there for both
omapdss and omapdss6.

We are working towards enabling omapdss6, which will consists of a new
dss, dispc and dpi drivers. omapdss6 will be a new module. The panel,
encoder and omapdrm will need to use either the current omapdss driver
or the new omapdss6 driver, depending on the platform.
This will be implemented with a common base module and function
pointers.
This patch adds a skeleton omapdss-base.ko module, to which we'll be
moving common dss functionality like registration of the panels.
