After this patch OMAP_DSS_BASE module is not including any OMAP2_DSS
headers, only the API omapdss.h. "sturct dss_data", the piece of the
data structure needed for base.c is defined in omapdss.h and added as
a member to struct dss_device, and later to struct dss6_device.
The patch is still a bit hackish. The struct dispc_device declaration
is currently shared between alternative dss implementations, with
different internal definitions. It should be relatively simple to use
a similar struct dispc_data as struct dss_data is for dss_device, move
some common parts - maybe the dispc_ops itself - there and find the
private data with container_of macro. Also the contents of struct
dss_data in side dss_device is currently redundant. These should be
easy enough to fix, if we decide to take this route.
