8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xx

The number of CPUs are getting detected dynamically by checking the
processor SVR value.  Also removed CONFIG_NUM_CPUS references from all
the platforms with 85xx/86xx processors.

This can help to use the same u-boot image across the platforms.

Also revamped and corrected few Freescale Copyright messages.
