Bluetooth: hci_qca: use wait_until_sent() for power pulses
wcn3990 requires a power pulse to turn ON/OFF along with regulators. Sometimes we are observing the power pulses are sent out with some time delay, due to queuing these commands. This is causing synchronization issues with chip, which intern delay the chip setup or may end up with communication issues.
