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 .
