fmradio: set timeout 10 seconds instead of 500 jiffies in FM char driver read and remove a printk on timeout

BZ: 33530

Set timeout as a multiple of HZ instead of jiffies in the FM char driver read function,
since jiffies may change with the kernel.
The timeout is set to 10 seconds as is done in the GPS char driver.
Also, do not log an error on read timeout, since it is not an error.
