powerpc: Remove empty giveup_altivec function on book3e CPUs
Use an empty inline instead of an empty function to implement giveup_altivec on book3e CPUs, similar to flush_altivec_to_thread. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
