Pass the physical address of the bootinfo block to the kernel in

Browse Source 
register r8. We continue to write the bootinfo block at the same
hardwired address, because the kernel still expects it there.
It is expected that future kernels use register r8 to get to the
bootinfo block and don't depend on the hardwired address anymore.

Bump the loader version once again due to the interface change.

0.3: Pass the physical address of the bootinfo block in register r8
to the kernel. Continue to put it at the fixed address for now.
0.2: Much improved version. Significant is the support for passing
the FPSWA interface pointer to the kernel.
0.1: Initial EFI version, germinated from the NetBSD i386
