firmware: mediatek: Add adsp ipc protocol interface
Some of mediatek processors contain
the Tensilica HiFix DSP for audio processing.
The communication between Host CPU and DSP firmware is
taking place using a shared memory area for message passing.
ADSP IPC protocol offers (send/recv) interfaces using
mediatek-mailbox APIs.
We use two mbox channels to implement a request-reply protocol.
