wifi: ath12k: Register various userPD interrupts and save SMEM entries

Q6 and ath12k driver communicates using SMEM and IRQs. Spawn interrupt
is triggered once the userPD thread is spawned. Ready interrupts denotes
userPD is completely powered up and ready. Stop-ack is to acknowledge
the ath12k driver that userPD is stopped. Ath12k driver needs to set spawn
bit in SMEM to instruct Q6 to spawn a userPD. Similarly stop bit is
set when userPD needs to be stopped.
