Revert "PM / sleep / ACPI: Use the ACPI_FADT_LOW_POWER_S0 flag"

Revert commit 08b98d3291 (PM / sleep / ACPI: Use the ACPI_FADT_LOW_POWER_S0
flag) as it caused system suspend (in the default configuration) to fail
on Dell XPS13 (9360) with the Kaby Lake processor.

The default suspend mode (ie. the one to be used without writing anything into
/sys/power/mem_sleep) is either "deep" (if Suspend-To-RAM is supported) or
"s2idle", but it can be overridden by the value of the "mem_sleep_default"

the information in the FADT, the default may be "s2idle" even if Suspend-To-RAM

The properties of all of the sleep states are described below.
