npu2-opencapi: Tweak fundamental reset sequence

Modify slightly the ordering of a few steps in our init sequence on
fundamental reset, so that it can be called from the OS, when the link
is already up:

- when the card is reset, the link goes down, so we need to fence the
  brick to prevent errors propagating to the NPU and OS
- since fencing and unfencing don't require any delay, let's also
  fence/unfence during the very first reset at boot. It's useless but
  doesn't hurt and keep the code simpler.
- resetting the PHY must be done a bit later, while fenced and the ODL
  and DLx in reset
