Mario Limonciello 811d59fdf5 ACPI: s2idle: Add a new ->check() callback for platform_s2idle_ops
On some platforms it is found that Linux more aggressively enters s2idle
than Windows enters Modern Standby and this uncovers some synchronization
issues for the platform.  To aid in debugging this class of problems in
the future, add support for an extra optional callback intended for
drivers to emit extra debugging.
