x86/asm/power: Create stack frames in hibernate_asm_64.S

swsusp_arch_suspend() and restore_registers() are callable non-leaf
functions which don't honor CONFIG_FRAME_POINTER, which can result in
bad stack traces.  Also they aren't annotated as ELF callable functions
which can confuse tooling.

Create a stack frame for them when CONFIG_FRAME_POINTER is enabled and
give them proper ELF function annotations.
