Wrong enable_mask when sending core enable IPC

[tlauda]

Wrong enable_mask is set for core enable IPC.
Kernel should keep track of how many cores should be currently enabled in order to handle this correctly.

Let's consider scenario, where the first pipeline in topology is scheduled on core 1 and the rest of them on core 0. Current flow:

1. Kernel sends IPC with enable_mask = 0x2 (core 1) for the first pipeline.
2. Kernel sends IPC with enable_mask = 0x1 (core 0) for the second pipeline.
   The second IPC disables core 1, because the appropriate bit is 0. It should have value 0x3 instead.

@ranj063 can you comment and/or describe how we might solve this? Wondering if this is a quick fix which can go in the next upstream batch or more time needed?

[tlauda]

@ranj063 Any updates?

[tlauda]

@plbossart @ranj063 Can we at least get estimates when it can be fixed?

[plbossart]

@ranj063 @tlauda is this issue still valid, we've merged a PR a while ago for this.

[ranj063]

@plbossart yes, this is fixed.
