arch/powerpc: Remove <linux/fb.h> from backlight code
Replace <linux/fb.h> with a forward declaration in <asm/backlight.h> to
resolve an unnecessary dependency. Remove pmac_backlight_curve_lookup()
and struct fb_info from source and header files. The function and the
framebuffer struct are unused. No functional changes.
v3:
* Add Fixes tag (Christophe)
* fix typos in commit message (Jani)
