misc: mic: scif: scif_fence: Fix a bunch of different documentation issues

Firstly add missing descriptions for every use of 'scifdev', then
correct incorrect formatting of existing function argument descriptions
changing to the expected format of '@.*: ', finally add missing
description for function argument 'mark'.

Fixes the following W=1 warnings:
