2c28e13d25 rtkit: add rtkit_{hibernate,sleep} and use them for DCP and ANS2 
s/IDLE/HIBERNATE/ to keep in sync with the Linux driver and then
hibernate DCP but send ANS2 to sleep to allow reusing both.

00404e9bc3 afk: propagate failures in afk_epic_rx correctly 
If the co-processor crashes afk_epic_poll will always fail which results
in afk_epic_rx getting stuck in an infinite loop calling afk_epic_poll
again and again.
This happens with e.g. old/incompatible DCP firmware.
Make sure the m1n1 proxy still works in those cases by propagating the
error correctly.
