Switch the order of LCD_CLASS_DEVICE and BACKLIGHT_CLASS_DEVICE,
so that it's possible to insert LCD devices without borking the
dependency displays of xconfig and other config tools.

Currently its possible to build the backlight core as a module yet
compile the drivers into the kernel which gives missing symbols.

Fix.

The backlight and lcd subsystems can be notified by the framebuffer layer
of blanking events.  However, these subsystems, as a whole, can function
independently from the framebuffer layer.  But in order to enable to the
lcd and backlight subsystems, the framebuffer has to be compiled also,
effectively sucking in a huge amount of unneeded code.

To prevent dependency problems, separate out the framebuffer notification
mechanism from the framebuffer layer and permanently link it to the kernel.

CONFIG_FB = m and CONFIG_{BACKLIGHT:LCD}_CLASS_DEVICE = y is possible
resulting in link errors.  Fix by making backlight and lcd class also depend
on FB

Generalise the Corgi backlight driver by moving the default intensity and
limit mask settings into the platform specific data structure.  This enables
the driver to support other Zaurus hardware, specifically the SL-6000x (Tosa)
model.

Also change the spinlock to a mutex (the spinlock is overkill).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
