powerpc64/sha256: adjust stack offset for storing non-volatile registers

According to the ABI, the stack pointer is quadword aligned, so starting
the stack storage at offset -8, may cause the return address to be
stepped on. Adjusting to use -16 as the starting point, which also
matches other POWER assembly code.
