Add get_ovl_name() and get_mgr_name() to dispc_ops and get rid of
adhoc names here and there in the omapdrm code. This moves the names
of hardware entities to omapdss side where they have to be when new
omapdss backend drivers are introduced.

The new omapdss API is HW independent and cleans up some of the DSS5
specific hacks from the omapdrm side and gets rid off the DSS5 IRQ
register bits and replace them with HW independent generic u64 based
macros. The new macros make it more straight forward to implement the
IRQ code for the future DSS versions that do not share the same
register structure as DSS2 to DSS5 has.

To: dri-devel; +Cc: tomi.valkeinen, laurent.pinchart, Jyri Sarha
From: Tomi Valkeinen <tomi.valkeinen@ti.com>
The new DSS6 driver needs some structs and defines which are currently
in dss.h, which is for the old DSS driver.
Move the required structs and defines from dss.h to omapdss.h.
