[PATCH 27/28] backlight: lcd: Remove struct fb_videomode from set_mode callback

[Thomas Zimmermann <tzimmermann@suse.de>]

Implementations of struct lcd_ops.set_mode only require the resolution
from struct fb_videomode. Pass the xres and yres fields, but remove the
dependency on the fbdev data structure.
