Subject: [PATCH 0/3] apple-nvme: bug and perf fixes

This small series fixes three unrelated issues with the Apple NVMe
driver.

* fix NVMe on firmware/machine
* fix a power domain leak
* fix pathological driver performance with random writes

The first two are strict bug fixes, the last is technically an
optimization but given the measured 200x performance difference I do
consider to be a fix ;-)

Given the early stage of mainlining for these SoCs, none of this needs
to be backported.
