cnss2: Add synchronized force wake support

Device is still possible to enter low power state with current
unsync force wake method, and it may cause later failure when
accessing SoC register.

Introduce sync force wake API and expose it to WLAN host driver,
which will ensure device won't enter low power state after
device_wake is asserted.
