dc9127e93a ipm: cavs_idc: use the IPC/IDC definitions in SoC 
The SoC definitions have the necessary IPC/IDC bits so there is
no need to define them separately.

492e890cd6 ipm: add driver for the CAVS DSP Intra-DSP Communication (IDC) 
This adds a rather primitive driver for use with the Intra-DSP
Communication (IDC) on the DSP on certain Intel SoCs. The IDC
generates interrupts from one core to another by writing to
certain registers. This is also being utilized as
the scheduler IPI since it can interrupt other cores.
