powerpc/boot: Only build OPAL code when necessary

Only build the OPAL console code in when necessary. This looks like it should use CONFIG_PPC_POWERNV, but because the opal-call.S code is 64-bit only, we must only build it when we're building the boot wrapper 64-bit. Signed-off-by: Michael Ellerman <[email protected]>
