staging/olpc_dcon: fix checkpatch warnings
The below checkpatch warnings was fixed,
- WARNING: Prefer pr_debug(... to printk(KERN_DEBUG, ...
- WARNING: Prefer pr_warn(... to printk(KERN_WARNING, ...
- WARNING: Prefer pr_info(... to printk(KERN_INFO, ...
- WARNING: Prefer pr_err(... to printk(KERN_ERR, ...
And added pr_fmt.
