[PATCH 3/3] acpi: s3: sleep for s3_min_delay after sending KEY_SLEEP

[Keng-Yu Lin]

Unlike `pm-suspend` only returns to fwts when the suspending
is completed, acpi_fakekey returns immediately after sending
the keycode while the system is still in middle of suspending.

So let fwts sleep for seconds of s3_min_delay after sending
the keycode.

Also increase s3_min_delay to 10 seconds.
