backlight: cr_bllcd: use pr_err()/pr_info() instead of printk()
Use pr_err()/pr_info() instead of printk() to allow dynamic debugging. The pr_fmt prefix for pr_ macros is used. Also fix checkpatch warnings as below: WARNING: printk() should include KERN_ facility level WARNING: Prefer pr_err(... to printk(KERN_ERR, ...
