ACPI suspend: Always use the 32-bit waking vector

commit a6629105dd03d370fcb31e97bddf223fa4bb651e upstream.

According to the ACPI specification 2.0c and later, the 64-bit waking vector
should be cleared and the 32-bit waking vector should be used, unless we want
the wake-up code to be called by the BIOS in Protected Mode.  Moreover, some
systems (for example HP dv5-1004nr) are known to fail to resume if the 64-bit
waking vector is used.  Therefore, modify the code to clear the 64-bit waking
vector, for FACS version 1 or greater, and set the 32-bit one before suspend.
