This series enables presence detection for opencapi devices on
platform where it's supported... Only zaius for now, but ZZ should be
around the corner.

It also reorders how we train the links, to use the PHB reset
callbacks. This is a first step to be able to reset the link from
linux.

Boot time is improved, especially on zaius.

Changelog:
v2:
	comments from Andrew (patch 1, 2)
	Add fencing/unfencing of the OTL during reset (patch 3)


Frederic Barrat (5):
  npu2-opencapi: Use presence detection
  npu2-opencapi: Rework adapter reset
  npu2-opencapi: Train links on fundamental reset
  npu2-opencapi: Cleanup traces printed during link training
  npu2-opencapi: Fix link state to report link down
