x86: move alloc and free coherent to common header
they are the same between architectures. (except for the fact that x86_64 has duplicate code) move them to dma-mapping.h Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
