x86-32, amd: Move va_align definition to unbreak 32-bit build
hpa reported that dfb09f9b7ab03fd367740e541a5caf830ed56726 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.
