[PATCH v2 7/7] backlight: progear: use pr_err instead of printk

[Jingoo Han <jg1.han@samsung.com>]

This patch uses pr_err instead of printk to allow dynamic debugging.
The pr_fmt prefix for pr_ macros is used. It also fixes checkpatch
warnings as below:

WARNING: printk() should include KERN_ facility level
