ACPI: do acpisleep dmi check when CONFIG_ACPI_SLEEP is set

The current acpisleep DMI checks only run when CONFIG_SUSPEND is set.
And this may break hibernation on some platforms when CONFIG_SUSPEND
is cleared.

Move acpisleep DMI check into #ifdef CONFIG_ACPI_SLEEP instead.

[rjw: Added acpi_sleep_dmi_check() and rebased on top of earlier
 patches adding entries to acpisleep_dmi_table[].]
