Up to now, the function is_serdes_configed() doesn't check if the map of serdes protocol is initialized before accessing it. The function is_serdes_configed() will get wrong result when it was called before the serdes protocol maps initialized. As the first element of the map isn't used for any device, so use it as the flag to indicate if the map has been initialized.

V2:
- Check initialization-state of the serdes protocol map before serdes init.
- Comment the element 'NONE' used as a initialization-state flag.
Zhiqiang,
This patch has been merged but I found an issue with it today. Please try to boot P4080DS from NOR flash. It causes recursive calls fsl_serdes_init()->p4080_erratum_serdes_a005()->is_serdes_configured()->fsl_serdes_init(). Please check if you have any similar recursive case for other platforms. Please send a fix ASAP.
