Use proper helper functions to copy the PCI ROM. Also use dynamic memory
allocation. The original code mapped incorrect amount of memory and will
crash on some platforms.

This will make them maintainable. Also, it now works on big-endian systems.

This is the slow path (done every 1+ second, per channel) so I guess
there is no need to cache the results.

I have removed CBR-related bits from the MPEG4 VOL header since we can't
do CBR (at least yet).

 - Move bl_val and bl_dev into dcon_priv struct....
 - The only time we ever read the backlight val from the dcon is
   at probe time.  Rather than calling dcon_get_backlight for that, just
   read from the register.
 - Drop dcon_get_backlight; it's just returning dcon->bl_val.
 - Rename dcon_set_backlight_hw to dcon_set_backlight, and drop the
   old dcon_set_backlight function.  Move contents of old dcon_set_backlight
   function into dconbl_set.
 - Shuffle backlight_ops callbacks around to be closer to struct, and
   rename them.
 - Make use of new backlight_properties arg to backlight_device_register,

Global variables dcon_switched, dcon_irq_time, and dcon_load_time can all be moved
into the dcon_priv struct now that dcon_interrupt has access to dcon_priv.
Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This moves dcon_source and dcon_pending into the dcon_priv struct.

Because these variables are used by the IRQ handler (which is
registered in the model-specific callbacks), we end up needing
to move dcon_priv into olpc_dcon.h.  This also changes the IRQ
registration to use the dcon_priv pointer as dev_id, instead of
dcon_driver.

This adds CONFIG_FB_OLPC_DCON_1 and CONFIG_FB_OLPC_DCON_1_5 options for
allowing selection of XO-1 and/or XO-1.5 DCON support.  In the process,
it also forces the xo_1.c and xo_1_5.c files to build as separate units,
correctly selects between XO-1 and XO-1.5 at runtime, and adds some
hacks to allow xo_1_5.c to build.

This isn't the cleanest patch, but it'll get better as more global
variables are dropped.

 - move fbinfo and ignore_fb_events into dcon_priv
 - add calls to {un,}lock_fb_info before calling fb_blank
 - fail to load the driver if there are no registered framebuffers

That last one fixes a potential oops, where if the dcon driver loads
without a framebuffer registered, fb_blank will end up being passed a
NULL (and will attempt to dereference it).
