ACPI hibernate: Introduce new kernel parameter acpi_sleep=s4_nonvs
On some machines it may be necessary to disable the saving/restoring
of the ACPI NVS memory region during hibernation/resume. For this
purpose, introduce new ACPI kernel command line option
acpi_sleep=s4_nonvs.
Based on a patch by Zhang Rui.
