mhi: core: timeout if sync power up fails to enter mission mode



When sync power up API is called, it does an asynchronous
attempt to power up with a timeout for mission mode entry.
If unable to enter mission mode in time, return -ETIMEDOUT
to clients so they can perform necessary clean-up actions.
