To make the transition in a piece-wise and bisectable way possible,
I've hijacked the ->owner_list from drm_sman. While transitioning, the
list_add was done by the driver, while the list_del was still done by
the dying sman code.
Now that we are in full control of ->owner_list, do the list_del
ourselves.
v2: Better explain the list_del trickery as suggested by Chris Wilson.

In contrast to kms drivers, sis/via _always_ associated a buffer with
a drm fd. So by the time we reach lastclose, all open drm fds are gone
and with them their associated objects.
So when sis/via call drm_sman_cleanup in their lastclose funcs, that
will free 0 objects.
The owner tracking now serves no purpose at all, hence rip it ou. We
can't kill the corresponding fields in struct drm_memblock_item yet
because we hijack these in the new driver private owner tracking. But
now that drm_sman.c doesn't touch ->owner_list anymore, we need to
kill the list_move hack and properly add the item to the file_priv
list.
Also leave the list_del(&obj->owner_list) in drm_sman_free for the
moment, it will move to the drivers when sman disappears completely.
v2: Remove the redundant INIT_LIST_HEAD as noted by Chris Wilson

By attach a driver private struct to each open drm fd.
Because we steal the owner_list from drm_sman until things settle,
use list_move instead of list_add.
This requires to export a drm_sman function temporarily before
drm_sman will die for real completely.

Call connector->funcs->dpms(DPMS_ON) rather than just setting
connector->dpms = DPMS_ON. This ensures that if the connector
has something to do to enable the output (rather than just using
drm_helper_connector_dpms helper directly), that this happens
at bootup. This solves an issue with connectors not getting
enabled from fbcon_init() when the driver is loaded.

If the bpc is set from the connector is 0, we then use it later to adjust
in a special case the HDMI pixel clock, however if the bpc is 0, we end up
passing a 0 pixel clock into the code.
I'm not sure if this is the correct answer or if we should avoid the HDMI
clock adjustment for 0 values.
This fixes a divide by 0 on my Llano system with a HDMI monitor and hdmi
