x86 PM: move 64-bit hibernation files to arch/x86/power

Move arch/x86/kernel/suspend_64.c to arch/x86/power .

Move arch/x86/kernel/suspend_asm_64.S to arch/x86/power
as hibernate_asm_64.S .

Update purpose and copyright information in
arch/x86/power/suspend_64.c and
arch/x86/power/hibernate_asm_64.S .

Update the Makefiles in arch/x86, arch/x86/kernel and
