[Skiboot] [PATCH v2 0/5] npu2-opencapi: Use presence detection and reset

[Frederic Barrat]

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)
