pnv/xive2: Add a get_config() method on the presenter class
The presenters for xive on P9 and P10 are mostly similar but the
behavior can be tuned through a few CQ registers. This patch adds a
"get_config" method, which will allow to access that config from the
presenter in a later patch.
For now, just define the config for the TIMA version.
