We already have a flag word to indicate the existence of MISC_ENABLES,
so use the same flag word to indicate existence of cr4 and EFER, and
always restore them if they exist. That way if something passes a
nonzero value when the value *should* be zero, we will still
initialize it.

The end signature was defined in wakeup_asm.S as it originally came
from the ACPI wakeup code. However, we rely on the existence of the
.signature section to expand .bss, otherwise we would have to include
code to explicitly zero the .bss depending on the configuration.
Since the expanded .bss is just in .init.data anyway, it's easier to
always have it expanded.
This fixes failures when compiled without CONFIG_ACPI_SLEEP.

Simplified hierarchy under rm directory to a flat
directory because it is not anymore really justified
to have own directory for wakeup code. It only adds
more complexity.
