All drivers to include the omapdrm/dss/omapdss.h header file. This header
includes the <video/omapdss.h>

Now that omapfb has its own copy of omapdss and display drivers, we can
move omapdss and display drivers which omapdrm uses to omapdrm's
directory.

We also need to change the main drm Makefile so that omapdrm directory
is always entered, because omapdss has a file that can't be built as a
module.

Since 39b2bbe3 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.

Also make use of gpiod_get*_optional where applicable.

Apart from simplification of the affected drivers this is another step
towards making the flags argument to gpiod_get*() mandatory.
