x86-32, amd: Move va_align definition to unbreak 32-bit build

hpa reported that dfb09f9 breaks 32-bit builds with the following error message: /home/hpa/kernel/linux-tip.cpu/arch/x86/kernel/cpu/amd.c:437: undefined reference to `va_align' /home/hpa/kernel/linux-tip.cpu/arch/x86/kernel/cpu/amd.c:436: undefined reference to `va_align' This is due to the fact that va_align is a global in a 64-bit only compilation unit. Move it to mmap.c where it is visible to both subarches.
