ACPICA: Do not use extended sleep registers unless HW-reduced bit is set
commit 7cec7048fe22e3e92389da2cd67098f6c4284e7f upstream.
Previous implementation incorrectly used the ACPI 5.0 extended
sleep registers if they were simply populated. This caused
problems on some non-HW-reduced machines. As per the ACPI spec,
they should only be used if the HW-reduced bit is set. Lv Zheng,
ACPICA BZ 1020.
