[PATCH][RFC] pm: remove bus_type suspend_late()/resume_early()

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm@igel.co.jp>

Remove the ->suspend_late() and ->resume_early() callbacks
from struct bus_type. These callbacks are legacy stuff at
this point and since there seem to be no in-tree users we
may as well remove them. New users should use dev_pm_ops.

 This patch is almost too good to be true so there must be
 something wrong. I did however spend quite some time grepping
 and I could not find any in-tree users.
