The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

DSS uses shared irq handlers for DISPC and DSI, because on OMAP3, the
DISPC and DSI share the same irq line.

However, the irq handlers presume that the hardware is enabled, which,
in theory, may not be the case with shared irq handlers. So if an
interrupt happens while the DISPC/DSI is off, the kernel will halt as
the irq handler tries to access the DISPC/DSI registers.

In practice that should never happen, as both DSI and DISPC are in the
same power domain. So if there's an IRQ for one of them, the other is
also enabled. However, if CONFIG_DEBUG_SHIRQ is enabled, the kernel will
generate a spurious IRQ, which then causes the problem.

This patch adds an is_enabled field for both DISPC and DSI, which is
used to track if the HW is enabled. For DISPC the code is slightly more
complex, as the users of DISPC can register the interrupt handler, and
we want to hide the is_enabled handling from the users of DISPC.

We don't have to update a backlight status every time a blanking or
unblanking event comes because the backlight status may have already
been what we want.  Another thought is that one backlight device may be
shared by multiple framebuffers.  We don't hope blanking one of the
framebuffers may turn the backlight off for all the other framebuffers,
since they are likely being active to display something.

This patch makes the backlight status be updated only when the relevant
backlight device's use count changes from zero to one or from one to
zero.

We don't have to update the state and fb_blank properties of a backlight
device every time a blanking or unblanking event comes because they may
have already been what we want.  Another thought is that one backlight
device may be shared by multiple framebuffers.  The backlight driver
should take the backlight device as a resource shared by all the
associated framebuffers.

This patch adds some logic to record each framebuffer's backlight usage
to determine the backlight device use count and whether the two
properties should be updated or not.  To be more specific, only one
unblank operation on a certain blanked framebuffer may increase the
backlight device's use count by one, while one blank operation on a
certain unblanked framebuffer may decrease the use count by one, because
the userspace is likely to unblank an unblanked framebuffer or blank a
blanked framebuffer.
