[PATCH] tty: serial: serial_core.c: printk replacement

[Sudip Mukherjee]

printk replaced with corresponding dev_err, dev_alert, dev_notice and pr_info.
pr_info has been used instead of dev_info as there is a check for port->dev being NULL or not.
fixed two broken user-visible strings used by the corresponding printk

For my previous patch ,Jiri Slaby told to investigate further as I have used uport->dev and there was a check for whether it is NULL. 
For this patch instead of uport->dev , i have used tty_dev as that one gave a better desciption of the device than uport->dev.
