struct omap_overlayr contains info and info_dirty fields, both of which
should be internal to apply.c.
This patch moves those fields into ovl_priv data, and names them
user_info and user_info_dirty.

Overlays are currently enabled and disabled with a boolean in the struct
omap_overlay_info. The overlay info is set with ovl->set_overlay_info(),
and made into use with mgr->apply().
This doesn't work properly, as the enable/disable status may affect also
other overlays, for example when using fifo-merge. Thus the enabling and
disabling of the overlay needs to be done outside the normal overlay
configuration.
This patch achieves that by doing the following things:
1) Add function pointers to struct omap_overlay: enable(), disable() and
is_enabled(). These are used to do the obvious. The functions may block.
2) Move the "enabled" field from struct omap_overlay to ovl_priv_data.
3) Add a new route for settings to be applied to the HW, called
"extra_info". The status of the normal info and extra_info are tracked
separately.
The point here is to allow the normal info to be changed and
applied in non-blocking matter, whereas the extra_info can only be
changed when holding the mutex. This makes it possible to, for example,
set the overlay enable flag, apply it, and wait until the HW has taken
the flag into use.
This is not possible if the enable flag would be in the normal info, as
a new value for the flag could be set at any time from the users of
omapdss.

With module.h being implicitly everywhere via device.h, the absence
of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the
device.h file, we need to explicitly include these files now.

Implement auto-update mode for manual-update displays. omapfb driver
uses a delayed work to update the display with a constant rate.
The update mode can be changed via OMAPFB_SET_UPDATE_MODE ioctl, which
previously called omapdss but is now handled inside omapfb, and a new
sysfs file, "update_mode".
The update interval is by default 20 times per second, but can be
changed via "auto_update_freq" module parameter. There is also a new
module parameter "auto_update", which will make omapfb start manual
update displays in auto-update mode.
This auto-update mode can be used for testing if the userspace does not
support manual update displays properly. However, it is a very
inefficient solution, and should be considered more as a hack for
testing than something that could be used as a long term solution.

When more than one memory region needs to be lockd at the same time use
the memory region id to fix the order in which the locks are taken. Also
one needs to use the _nested() versions of the locking primitives. The
memory region id can serve as the lock class there as well.

Separate the memory region from the framebuffer device a little bit.
It's now possible to select the memory region used by the framebuffer
device using the new mem_idx parameter of omapfb_plane_info. If the
mem_idx is specified it will be interpreted as an index into the
memory regions array, if it's not specified the framebuffer's index is
used instead. So by default each framebuffer keeps using it's own
memory region which preserves backwards compatibility.
This allows cloning the same memory region to several overlays and yet
each overlay can be controlled independently since they can be
associated with separate framebuffer devices.

Move update() and sync() from omap_dss_device to omap_dss_driver.
Also, update was hardcoded to use virtual channel 0. This patch adds a
parameter that specifies the VC.
This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.
