npu2-hw-procedures: Move some opencapi PHY settings in one-off init

The PHY_RX_AC_COUPLED and PHY_RX_SPEED_SELECT for opencapi are group
settings for the obus. They should be set in the one-off PHY init
function at boot and not on the link reset path, as they theoretically
impact more than one link.
Since we cannot mix link type and/or speed on an optical bus, it has
no pratical impact, it just looks cleaner.

Also use the OCAPIINF macro for the associated traces.
