core/direct-controls: wait for core special wkup bit cleared
When clearing special wakeup bit on a core, wait until the
bit is actually cleared by the hardware in the status register
until returning success.
This may help avoid issues with back-to-back reads where the
special wakeup request is cleared but the firmware is still
processing the request and the next attempt to set the bit
reads an immediate success from the previous operation.
