linux-raspberrypi.inc: Make kgdboc kernel param optional

Browse Source 
The kernel debugger over console (kgdboc) parameter is being added
unconditionally to the kernel command line but this means that the
kernel will stop and wait for gdb to attach in case of a exception
or when sending a sysrq-g key. This behaviour may not be what most
users wants that are not remotely debugging the kernel over serial
console so make it optional by adding a ENABLE_KGDB config option.
