sparc64: Adjust KTSB assembler to support larger physical addresses.

[ Upstream commit 8c82dc0e883821c098c8b0b130ffebabf9aab5df ]

As currently coded the KTSB accesses in the kernel only support up to
47 bits of physical addressing.

Adjust the instruction and patching sequence in order to support
arbitrary 64 bits addresses.
