edd: add default mode CONFIG_EDD_OFF=n, override with edd={on,off}
Add a kernel parameter option to 'edd' to enable/disable BIOS Enhanced Disk Drive Services. CONFIG_EDD_OFF disables EDD while still compiling EDD into the kernel. Default behavior can be forced using 'edd=on' or 'edd=off' as a kernel parameter.
