arm64: sunxi: adjust default load addresses 

As arm64 has slightly different expectations about load addresses, lets
use a different set of default addresses for things like the kernel.
As arm64 kernels don't come with a decompressor right now, reserve some
more space for really big uncompressed kernels.
