Add acpi_get_sleep_type() to i82371eb and P2B _PTS/_WAK methods
Build fix for src/arch/i386/boot/acpi.c if !CONFIG_SMP
Also check for acpi_slp_type 2 in acpi_is_wakeup, since S2
uses the same acpi wakeup vector as S3.
Add _PTS/_WAK methods to turn off/on the CPU/case fans and blink
the power LED while sleeping.
acpi_get_sleep_type() is in a seperate file i82371eb_wakeup.c because
it is used in both romstage and ramstage after patch 3/3, whereas
i82371eb_early_pm.c is used only in romstage.
I used the name acpi_get_sleep_type instead of acpi_is_wakeup_early
because I think acpi_is_wakeup_early is a bit misleading as a name since it
doesn't return a boolean value.
Other chipsets so far only ever set acpi_slp_type to 0 and 3, so the
added check for acpi_slp_type == 2 (resume from S2) should not
change behaviour of other boards:
