ASoC: SOF: amd: Use semaphore register to synchronize ipc's irq

2022-03-07T13:12:49Z

Add lock and unlock around ipc irq handling code using hw semaphore register that exhibit special property for register read calls. As host and DSP firmware uses few shared registers, there is a possible race condition around those shared registers values. This lock ensure synchronization between Firmware and host ipc interrupts.
