Enable platSpecialWakeup during IPL time and add support

Previously we only supported platSpecialWakeup at runtime because
we were not worried about needed special wakeup as the cores would
not go into stop state during the IPL. However, now PM code is expecting
bits to be set by the p9 special wakeup hwp so we need to call it during
the IPL. This code makes the handleSpecialWakeup.C/H files compatible
with IPL time build environment and enables the call on the IPL time path
