dc0d4ed26d ASoC: SOF: amd: Use semaphore register to synchronize ipc's irq 
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.
