staging: olpc_dcon: clean up backlight handling
- 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,
drop old code that set this manually.
