David Gibson 4f9242fc93 spapr: Make DRC reset force DRC into known state
The reset handler for DRCs attempts several state transitions which are
subject to various checks and restrictions.  But at reset time we know
there is no guest, so we can ignore most of the usual sequencing rules and
just set the DRC back to a known state.  In fact, it's safer to do so.

The existing code also has several redundant checks for
drc->awaiting_release inside a block which has already tested that.  This
patch removes those and sets the DRC to a fixed initial state based only
on whether a device is currently plugged or not.

With DRCs correctly reset to a state based on device presence, we don't
need to force state transitions as cold plugged devices are processed.
This allows us to remove all the callers of the set_*_state() methods from
outside spapr_drc.c.
