hid: hid-picolcd: Remove struct backlight_ops.check_fb

Update the driver to initialize struct fb_info.bl_dev to its backlight
device, if any. Thus rely on the backlight core code to match backlight
and framebuffer devices, and remove the extra check_fb function from
struct backlight_ops.

v2:
	* protect against CONFIG_FB_BACKLIGHT (Javier, kernel test robot)
	* reword commit message (Daniel)
