drm/nouveau: Reset AGP before running the init scripts.
BIOS scripts usually make an attempt to reset the AGP controller,
however on some nv4x cards doing it properly involves switching FW off

accordingly (e.g. with the corresponding calls to agp_enable()) we
will be locking ourselves out of the card MMIO space. Do it from
nouveau_mem_reset_agp() before the init scripts are executed.

drm/nouveau: tidy connector/encoder creation a little
Create connectors before encoders to avoid having to do another loop across
encoder list whenever we create a new connector. This allows us to pass

This can also potentially modify the connector ordering on nv50. On cards
where the DCB connector and encoder tables are in the same order, things
will be unchanged. However, there's some cards where the ordering between
the tables differ, and in one case, leads us to naming the connectors
"wrongly".

drm: implement helper functions for scanning lru list
These helper functions can be used to efficiently scan lru list
for eviction. Eviction becomes a three stage process:
1. Scanning through the lru list until a suitable hole has been found.
2. Scan backwards to restore drm_mm consistency and find out which
objects fall into the hole.
3. Evict the objects that fall into the hole.
These helper functions don't allocate any memory (at the price of
not allowing any other concurrent operations). Hence this can also be
used for ttm (which does lru scanning under a spinlock).
Evicting objects in this fashion should be more fair than the current
approach by i915 (scan the lru for a object large enough to contain
the new object). It's also more efficient than the current approach used
by ttm (uncoditionally evict objects from the lru until there's enough
free space).
