Add a new ELF segment .openbsd.bootdata to the sparc64 kernel.
This can be used to pass boot parameters to the kernel which can't be passed
safely via the Open Firmware interface, such as softraid volume IDs and keys.
The kernel already reads the arguments if available but ofwboot won't provide
them until further changes are committed there.
With support from deraadt, kettenis and matthew.
