[PATCH v2 0/2] nvme-apple: Fix suspend-resume regression

[Janne Grunau]

c76b8308e4c9 removed a NVMe controller reset in the shutdown path. This
broke suspend since it triggered a reset on resume. This reset hangs
since the co-processor is not up.
In addition the reset is needed on suspend to shutdown the co-processor
cleanly.

This series contains a functional revert of c76b8308e4c9 (a simple revert
is not possible due to other changes) and issues the NVMe reset only when
the co-processor is running.

Changes since Hector's v1:
- keep the fix localy in nvme-apple
- disable on shutdown for clean co-processor shutdown
- disable on reset only while the co-processor is running
